NOOP v12.0.0

A major release about choice and about honesty. Today can be drawn two different ways, a WHOOP 4.0 can
hand its heart rate to any app on your phone, daytime stress is measured against your own baseline
rather than a population's, and NOOP speaks a tenth language. Behind that, a long run of readouts that
had been claiming slightly more than they could attribute now say only what they know.

Today, drawn your way

• Ring gauges or liquid vessels (#2311, #2320, thanks @andigandhi). Today's gauges can be rings or
  the liquid vessels, chosen per device, on Android and on Apple. Reduce Motion is honoured in both.
• The hero ring, cleaned up (#2410, #2374, #2421, thanks @mailingjash). It draws flat rather than
  through a bloom stand-in, its label sits centred on the ring rather than beside it, and the active
  strap's own battery appears in the Liquid header.
• Nothing redraws while nothing moves (#2444, thanks @UtkuDenizAltiok), so the sky and the rings
  stop re-rendering between ticks.
• A Today-only Key Metrics view (#2601, thanks @kavemang), and the Key Metrics header no longer
  names a window it is not drawing (#2377, thanks @andremiliano).
• Swipe the day the same way on both platforms (#2379, thanks @andremiliano).

Your strap's heart rate, in any app

• Direct Bluetooth heart-rate broadcast on WHOOP 4.0 (#2400, thanks @don86nl). A 4.0 can advertise
  the standard heart-rate profile, so another app on your phone reads it live. The Today row says
  Partly rather than Yes, because the 4.0 offers the broadcast and not the rest of what a strap does.
• A link that reports its shape (#2399, #2429, #2436, #2411). The epitaph carries the signal shape
  rather than only its last reading, a false start-of-frame is rejected by its own header checksum, the
  peripheral is asked for again once the radio is up instead of scanning for one already bonded, and an
  OS-level strap link is adopted from either WHOOP family.
• A strap last seen low that has not been heard from since now says so, rather than going quiet.

Daytime stress, measured against you

• A personal daytime lens (#2125, #2430, #2431, #2432, #2452, thanks @bartmuskala). Resolved once a
  day instead of once per surface and anchored to real local days. The line ramps down the chart rather
  than across the day, and hours masked by activity now say why they are masked.
• Today honours the same baseline the detail screen does (#2450, #2504, thanks @kavemang), and it
  loads faster. It stays opt-in and off until you ask for it.
• The LF/HF ratio prints through the same arithmetic on both platforms (#2369, thanks @ayiskakov).

ECG on WHOOP MG

• The R17 layout corrected, along with its wrist values and its START list.
• Android drives the turn-on probe Apple already had, an in-flight offload is cleared before a
  realtime trace is requested, and the capture-may-be-running latch survives an app restart and reaches
  the Devices card.

Language

• Italian (#2454). NOOP's tenth language.
• Russian that counts properly. Grammatical plurals across the app, the Watch complications and the
  Apple catalogues, so counts take the right form instead of always one. Eight mistranslated Android
  strings are corrected, and the copy a widened scanner surfaced is localised.
• The coverage gate is diff-scoped again (#524, thanks @digitalerdude), and a push is compared
  against the tip before it rather than against itself (#2329).

Sleep

• A deep base prior of 0.15, on PSG evidence (#2576, thanks @UtkuDenizAltiok), scored subject by
  subject rather than in aggregate.
• The hypnogram read-out matches its own rows, in order and in value, and stage rows align with
  chart depth.
• Two sources recording one night are collapsed (#2550, thanks @kavemang), and the dedup heal's
  bank-recency witness is handed to the computed id alone (#2372).

Oura

• A ring that keeps its place (#2442, #2455, #2457, #2433, #2443, thanks @pipiche38). A sleep-window
  stash survives a reconnect, an interrupted drain banks its resume cursor so the next connect does not
  store again what it already holds, and a night the drain served twice is readable.
• A hypnogram tail that is padding, not time (#2564, thanks @pipiche38), so a pass no longer shifts
  early, and the ring's final pass no longer loses to an older one.
• A read crossing wake keeps the daytime beats (#2624, thanks @pipiche38), chosen per hour so a
  day-wide read does not swap channels.
• Experimental all-day heart rate and HRV holds its daytime arming for the learned night rather than
  for every screen-off (#2412).

Charge

• A breakdown that agrees with its headline (#2466, thanks @andremiliano). It reads the headline's
  own baselines rather than resolving a second set, and there is now a written rule for which nights a
  Charge baseline reads.
• An old WHOOP import no longer anchors the baselines (#2666, thanks @DX23876).

A quicker Apple app

• Ten performance changes (#2633, #2634, #2635, #2636, #2637, #2639, #2640, #2641, #2642, thanks
  @AlexSchmidt1999). Live Today Effort computes off the main actor, resolved Trends windows are reused
  across unrelated publications, HealthKit observer deltas are bounded to the recent sync window, shared
  chart styles resolve once per content update, full-resolution chart selection uses a date-ordered
  lookup, and the shared panel background composites fewer layers.
• Re-score passes that behave in the background (#2612, #2616, thanks @UtkuDenizAltiok and
  @kavemang), spaced at least thirty minutes apart and claiming their pass before a store await.

Shortcuts, Health and the Lock Screen

• A recorded GPS route through Shortcuts (#2340, thanks @rodrigosa7), as GPX or FIT, and the picker
  says what a FIT leaves out.
• Apple Health export names its chart heart-rate sources and refreshes write authorization.
• Android reads your profile weight from Health Connect (thanks @paradix86).
• One Lock Screen switch per thing NOOP shows, each touching only its own.

Smaller corrections

• Android honours your selected accent in Material controls (#2627) and rejects a malformed custom
  RGB value.
• Vital dates carry their weekday (#2622, thanks @kavemang).
• Today explains when Start session is available, and the Sleep movement strip says its scale is
  per-night.
• Deep Timeline zoom and pan stop snapping back (#2368, #2382, thanks @andigandhi), with x-axis
  labels and per-minute zoom ticks on both platforms.
• Saved-workout overlap suppression is measured rather than guessed at (#2527, thanks @kavemang),
  ahead of choosing a duration-aware threshold.

Still open

WHOOP 5/MG history remains unsolved, and the cause is now established rather than suspected: the strap
refuses the pairing handshake outright, so it is never given a clock, and an un-clocked 5/MG does not
persist sensor data to flash. Its offloads complete empty. Live heart rate works; the backfill cannot,
until the handshake does.

What's Changed

• feat(rescore): log a pass's CPU time and assertion expiries beside its elapsed time by @Iskrata in #2297
• fix(oura): watch the auth handshake — an unanswered get_nonce is retried, toggled, then dropped, never left "Connected" by @pipiche38 in #2307

NOOP v11.8.0

A release about doing more on the strap itself, and about turning off the parts you do not want.

A gym log book, advanced from your wrist

NOOP now carries an on-device lift log. Build a session, and move between sets with a double-tap on the
strap rather than picking the phone up mid-set. It is stored in a new schema with a matching Room twin
on Android, and the set metrics are computed by the same engine on both platforms rather than by two
that can drift apart.

A Coach that switches off

The AI Coach now has a single master switch. Turning it off retires the tab, the generated brief, the
home-screen widget and the tray notification, and it stops every request that would otherwise leave the
device. This is the whole feature going quiet, not just the screen being hidden.

Its settings moved onto their own screen rather than sitting in a crowded list. Android gained the
bottom-bar tab that iPhone already had, Disconnect is now somewhere an iPhone can reach, the current
OpenAI models are offered with the catalogue kept up to date, and a rate-limited request shows what the
provider actually said instead of a generic failure.

Sync the strap from a shortcut

A Sync Strap App Intent runs a sync from Shortcuts, the Lock Screen or a Home Screen button. A Live
Activity shows the offload while it runs, and an optional setting keeps the screen awake for as long as
it takes.

Reconnecting when the app is off-screen changed underneath that. iOS throttles background scanning hard
enough that a strap could sit undiscovered for minutes and then appear seconds after the app came to the
foreground. NOOP now asks for the last strap by name in the background, which iOS does honour, and keeps
scanning in the foreground so a strap you have switched to is still found.

Workouts that are easier to keep tidy

Sessions shorter than a minute are discarded rather than cluttering the list, and the list itself splits
into Current and Archived so a long history stays navigable. Deleting a workout now clears it from every
namespace the list reads, including the copy Apple Health had kept after the store let go of it.

The WHOOP sports that were missing are selectable, and the icons those exposed are fixed.
Auto-detection no longer saves anything on its own: it asks, and waits.

Readings that admit when they failed

A failed WHOOP 5 flag read was being reported as though it were a value. It now says it failed, on both
platforms. The frame integrity verdict reaches every consumer intact rather than being narrowed on the
way through, and the strap family NOOP records is the one the connection actually established rather
than the one it initially picked.

On Oura, a notification that tiles exactly into several packets is now read to the end instead of
stopping at the first. A young ring no longer adopts an anchor unit ten times too large, settled by
adjacency rather than assumption, and a diagnostic reports which ring epoch each sidecar row believes
in.

Charts that stop redrawing everything

Workouts and Sleep were re-evaluating their entire screens on every live heart-rate tick, roughly once a
second whenever a strap was connected. They no longer do. Three charts that had no hover gained a
tooltip, two uncapped series are downsampled before drawing, the sleep motion trace computes its peak
once rather than per epoch, and the Apple stress level rounds the way Android's already did.

The steps charts are clearer, with an optional 30-day average card.

Apple Health that keeps up

A re-score that was deferred now publishes to Apple Health once it lands, rather than being missed
because the publish already ran. Workouts are observed for live delivery, and a pass running in the
background paces itself under the CPU limit iOS enforces instead of being killed by it. A CSV import no
longer turns a correct SDNN into RMSSD on the way back out.

Localization

Chinese is complete in both scripts, across the app and the watch complications. The French recovery and
strain words are repaired, and the theme picker says light rather than lightweight.

A gap that had been letting UI copy ship English in every locale is closed. The scan that checks whether
a string has a catalogue entry was not looking at the spelling the codebase tells you to prefer, so
nothing reported strings that had none. Closing it surfaced the Home screen's own labels and the terms
you agree to on first launch, both of which are now translated.

NOOP v11.7.0

A release about the app keeping up with you, and about readings meaning what they say.

A stress screen that keeps up

Scoring a day of stress reads hundreds of thousands of samples. That work was happening on the same
thread that draws the screen, so Today and Stress could sit unresponsive while they loaded. It now
runs off that thread on both platforms, the baseline is reduced a day at a time rather than held a
month at once, and the unprompted rescore yields to whatever you are doing instead of competing with
it for the machine.

The home-screen widget fills on its own schedule without the app being opened. A rescore that produces
nothing is retried rather than being allowed to spend the whole refresh interval, and the Today curve
is kept as fresh as the screen it links to.

The readings themselves now agree with each other. The 0 to 3 level has one spelling across the widget
and the card, and is no longer rounded a second time on its way to the widget. The screen draws its
line from the same sliding read the number is taken from. Movement is drawn as the stretches it
actually covers rather than as dots on the axis. An early morning says the day has not started rather
than reporting Calibrating, which reads like something is wrong.

WHOOP 5 readings in the units the strap sends

Thanks to @Trillient, two decoding faults are corrected.

R-R intervals arriving on the standard heart-rate profile were converted as though they were in the
Bluetooth spec's units. A WHOOP 5 sends milliseconds directly, so every interval taken from that
profile came out 2.3% low, and HRV computed from it inherited the error. What settled it was a paired
capture: the same beats arriving on both the strap's own channel and the standard one carry
byte-identical values, so only one of the two conversions could be right.

The console log's record header was read as a 16-bit counter spanning two bytes. Only the first is a
counter, and it wraps at 255. Across 2,978 records from a single night the second byte never moved
through nine of those wraps, which a real counter could not do. Both platforms now decode the two
fields separately.

An Oura ring that stops repeating itself

Thanks to @pipiche38 for a sustained run of corrections to the ring's history path.

A replayed burst that the ring's own clock disproves as a reboot no longer resets the history resume
cursor, and no longer announces a reboot that did not happen. A night that has just been offloaded is
scored immediately rather than waiting for the next periodic tick. History is fetched every five
minutes rather than every fifteen, the anchor check judges a ten second gap rather than only a thirty
second one, and an onset rekey is refused when the assembler's own clip never bound.

There is also a feature-mode control and a consolidated set of Oura diagnostics in the Test Centre,
the raw night sidecar stays in the export, and the SpO2 sample keeps only the channel that carries a
reading.

Scores that survive a re-score

Thanks to @bhelm. WHOOP 5 HRV and Recovery, and the vitals derived from R-R, were being dropped by a
re-score pass that could not recompute them, so a value you already had could disappear on a pass that
had nothing better to put in its place. Both are now preserved.

Readings that say when they are at a limit

A Fitness Age resting at the end of its scale now says so, rather than presenting a bound as though it
were a measurement, and points at the number that still moves when the age stops. On Sleep, a night
already detected and staged no longer sits under a banner claiming it is still being calculated, and
browsing back to a night with no stage data no longer shows the most recent night's date beneath it.

Diagnostics that name the cause

A device reporting no R-R now says whether the beats were never banked or were refused by the unit
policy, which are different problems with different answers. The nightly HRV summary says why it
reported nothing. A retired probe tells whoever reads its output which switch to turn on, and stops
under-reporting its own retirement. A re-arm clears a refusal latch that previously could not be
reached once set. The sync chip surfaces the strap's backlog.

Thanks

Thanks to @pipiche38 (Oura history, replay judgement, diagnostics and export), @Trillient (WHOOP 5
R-R units and console sequence decoding), @bhelm (preserving legacy HRV, Recovery and R-R vitals),
@kavemang (tile values that shrink rather than truncate, per-signal illness baselines, Android
guards), and @digitalerdude (parity tooling on macOS, sync chip backlog, and documentation that
describes what the code returns).

NOOP v11.5.0

A release about NOOP holding a thread: in the coach, in the charts, and in what the strap log is willing
to claim.

A coach that keeps the thread

The coach was a single question and a single answer. It now behaves like something you can return to.

Replies stream in as they are written, so a long answer starts being readable immediately instead of
appearing all at once at the end. The conversation persists between sessions, so you can put the phone
down and pick the thread back up. It can speak its answers, and take a question by voice. A morning brief
sums up the night behind you without being asked.

There are home-screen widgets and Siri shortcuts for the things worth reaching in one step, and an
optional Today launcher card, requested in #1862 by @kggreco11, which stays off until you turn it on.

Your heart rate on the home screen

A widget showing live bpm with the recent trace behind it, on both platforms. It lets the launcher decide
the layout rather than assuming a size, so it sits properly wherever you put it.

Charts that claim less

Four things were wrong at once, and each made the others harder to see.

Points were spaced evenly regardless of date, so a fortnight you did not wear the strap looked the same
as two consecutive nights. Points are now spaced by date, and a gap takes the width it spans.

Every metric was drawn as though it were maximally volatile, which flattened the ones that genuinely move
and exaggerated the ones that do not. Scales are anchored per metric now.

Daily scores were drawn as lines. A line between two daily scores asserts the value travelled through
everything between them, and for a score computed once a day that is simply false. On a series that
swings twenty points overnight it is most of what reads as noise. They are bars now, and a day with no
reading is an empty slot of the right width rather than a plunge to zero.

And the Line and Bars setting in Settings only ever reached the Trends tab. It now applies to the detail
chart you reach by tapping a ring on Today, which is where most people were looking at it.

Alongside that, HRV and Resting HR carry a dashed rule at your own baseline. An absolute HRV number says
little on its own: 42 only means something once you know your normal is 54. The rule is drawn from the
same fold the vitals grid bands against, so the chart and the tile beside it cannot disagree, and it stays
hidden until the baseline has enough nights to be worth trusting.

Skin temperature, as a temperature

Skin temperature was shown as a deviation from baseline, which is the right number for spotting illness
and the wrong one for answering what your temperature is. It now leads with the measured value, with a
Settings choice if you prefer the difference, and the preference applies across the window rather than
only the newest night. Reported in #622 by @bartmuskala.

A Fahrenheit import used to be stored as though it were Celsius. It is converted on the way in now, which
was #111 from @whisp0.

Sleep

A night that the detector chopped into fragments, each too short to count on its own, scored as no night
at all. Those fragments are bridged back into the night they were, reported in #1937 by @bartmuskala.

The filled hypnogram can be dragged to read the clock time under your finger, asked for in #1855 by
@AussieFries. Its axis no longer mislabels a partial timeline as beginning at onset.

A night measured from heart rate alone now reports the HRV it actually measured rather than nothing, and
the Sleep tab stamps a carried value with the day it came from, so an older night can no longer read as
yesterday.

Steps and the day boundary

Step counting and the day boundary now follow your own sleep rather than the clock, so a late night stops
splitting one day's activity across two. The steps calibration also says which half of its input is
missing: asking for phone-step days is no help when what is absent is strap movement.

A wake time for each day

Weekday and weekend wake times can differ. The per-day override drives the strap alarm and the backup
notification too, not only the phone alarm.

Re-scores that take a fraction of the time

Re-scoring re-read sixty days of movement on every pass to fit one steps coefficient, whether or not any
of it had changed, and threw the answer away on every restart. It now re-folds only the days whose
movement actually moved, and keeps what it learned across launches. On a worn library that phase dropped
from roughly thirty-three seconds to under three. Reported in #1538 by @justinjor-bit.

The per-day work behind it is measured now rather than estimated, so the next thing worth speeding up can
be chosen from a number instead of a guess.

The strap log stops guessing

A connection your own phone was holding could be reported as the strap refusing to pair, which sent
people chasing a pairing problem that did not exist. Reported in #1997 by @semoi.

A non-active strap could be scanned, connected and drained while the one you selected sat idle. The strap
you chose is the one that gets connected and credited, from #1881 by @pipiche38.

A bond that ends now records why, in wording that reads the same in every language, and a disconnect
records how long the link held and whether anything was banked. Serial numbers are masked wherever a log
might be shared, including the hex-hidden ones.

Languages

Russian joins the supported locales. The German copy has been converted from the formal Sie to the
informal du throughout. A Portuguese string that a find and replace had corrupted is correct again.

Smaller things

Routes import from Apple Health and Health Connect (#1205). The battery pack reports its own charge
without overriding the strap's gauge, from #1935 by @Zebsi235. Body measurements and exercise distance
carry separate unit preferences, asked for in #1913 by @kavemang. The readings table prints each unit
once, reported in #1942 by @Geg0r. Rest says it is provisional while history is still syncing rather than
hiding itself. Tapping a hero ring on Today opens that metric's detail. The bottom bar can overlay the
content and hide itself as you scroll, on both platforms.

NOOP v11.0.0

A major release, and the version number is about one thing above all: the WHOOP 5.0 and MG finally hold
a connection. Everything else — a body clock on the Sleep screen, nights that read straighter, a Journal
that stops counting silence against you — arrived alongside it.

The WHOOP 5.0 / MG connection

A handshake the strap never answers no longer takes the link with it (#1635, #1642, thanks
@Zebsi235). NOOP wrote a CLIENT_HELLO on every connect and the 5/MG never acknowledged it; roughly
4.8 seconds later the link dropped, and the cycle repeated all day. NOOP now recognises the pattern,
stops writing the handshake for that strap, and keeps the link — the "Live HR, not fully paired" state
the app already modelled, reached deliberately instead of never. A field capture confirmed a link held
for over seven hours where it previously lasted five seconds.

An HCI capture contributed by @Zebsi235 settled what the strap is actually doing: it answers the
pairing request with Pairing Not Supported. That is a refusal, not a timing problem, and it ended
weeks of guessing.

Reconnecting costs what it should (#1778, #1779, #1781). Tapping Connect used to throw away
everything NOOP had learned and re-earn it over five more dropped links. It now keeps that knowledge,
gives the handshake exactly one fresh attempt, and settles after a single reconnect. A timer firing is
no longer treated as you asking to try again.

The strap is asked properly, and says so in the log (#1639, #1646, #1648, #1652, #1653, #1656,
#1668). NOOP now observes the OS pairing flow rather than inferring it, reads the Device Information
Service on a strap that never bonds, enumerates what a strap actually offers once per device, and lets
a 5/MG identify itself instead of being guessed at from its serial.

Clearing a stale phone pairing (#1790). When the phone holds a pairing the strap no longer honours,
NOOP can now clear it for you — off by default, in Test Centre, once per streak, and only after the
guide has already asked you to do it by hand.

Sleep

Your body clock (#1722, #1723, #1726, #1729, #1731, #1733). A 24-hour dial on the Sleep screen
showing your circadian phase, with an absolute chronotype bucketed from it. The diagnostics report the
inputs it used, and a rhythm too small to be real is refused rather than drawn.

A partial night is not a whole one (#1717, #1721, #1734). A hypnogram that only partly downloaded
was scored as though complete, which quietly shortened nights after an interrupted sync. Both readers
of that coverage now agree on what "complete" means.

Fragmented nights are stitched back together (#1755, #1782). When data is sparse, NOOP bridges
short gaps between sleep runs — and now allows a longer interruption when your heart rate stayed in the
sleep band throughout, because on a strap with no motion data heart rate is the better witness.

Sleep debt you can act on (#1741). Debt is now expressed as a target for tonight rather than an
abstract ledger.

Journal, workouts and metrics

Yes days are compared against No days (#322). Previously an insight weighed the days you logged
against every day you did not — so a week you never opened the app counted as a week of No.

Pause and resume a live workout (#1690). The controls are on the active-workout card, and the five
clocks that used to ignore a pause now honour it.

Latest Workouts opens a session (#1701, #1703). Tapping a row goes to its detail, and iOS uses the
same 14-day window Android already did.

Skin temperature leads with the absolute (#1663, #1665, #1671, #1708). The nightly absolute is
stored and shown first, deviation beneath it, in your own units throughout.

VO₂max says why a line breaks (#1740). The chart shows the decimal it draws, and explains a gap
rather than leaving one.

Straps, sync and privacy

Multiple straps are kept apart (#1455, #1634, #1730, #1745). Physiology is read across every
registered strap, firmware is attributed to the strap it came from rather than the last to connect,
last-sync belongs to a strap rather than the install, and a 5/MG carries a stable identity derived from
its serial.

Health Connect permissions by category (#1509, thanks @kavemang). Recovery and wellness, Activity,
and Body composition are picked before Android's prompt. Existing installs are detected and keep every
category they already had.

A crash you can report (#1718, #1720, #1724). Android shows a copyable recovery screen after a
crash, redacted everywhere it leaves the device — and an upgrade no longer greets you with a crash from
the build it replaced.

Update checking, on by default (#1674, #1675). Both platforms notice a new release. The privacy
documentation now describes what actually happens.

Experimental self-hosted push (#1631, #1700). One-way push to your own endpoint, off by default,
with the destination errors localized.

Oura

A bonded ring with no advertised name is listed again (#1776, thanks @pipiche38). A bonded ring
often stops advertising a name, and that was exactly the ring the Add-Device screen could not show.

Skin Temp as a Key Metrics tile (#1678), and protocol corrections (#1629, #1687, #1777).

Under the hood

Raw 100 Hz IMU capture and labeled recording sessions for the 5/MG (#1709). A JSON query CLI for the
local read tools (#1752). Analysis reads each row once instead of 2.25 times (#1695, #1696). Swift
analytics tests run on Linux (#1529). Several diagnostics now say which gate refused a metric, rather
than leaving a blank.

Thanks to @bhelm, @pipiche38, @kvnloo, @Zebsi235, @kavemang, @fadkeprasad, @Meriquium and @dwehrmann
for contributions in this release.

NOOP v10.6.0

A release about choosing how your training is scored, giving hardware back the time it needs to do its
own job, and stopping the phone from doing work it was never going to finish.

Effort, on a scale you pick

Banister TRIMP, wired end to end and selectable (#1562, #1563). Effort has always been a
thresholded Edwards score. Banister TRIMP is now a first-class alternative, complete with its own
log-map denominator (#1561) rather than borrowed constants, and the docs no longer claim NOOP uses a
method it did not. The toggle sits where someone looking for it would look (#1580).

A workout is scored against the day's HRmax (#1565). A session used to be able to score against a
different maximum than the day containing it, which made a hard workout and a hard day disagree. The
strap log now also records what each workout's Effort was scored against, and whether the strap saw the
session at all (#1566) — and when a day detects no workout, it says which gate ate it (#1574).

The phone stops re-scoring all night

A background re-score that can finish (#1557). A re-score that ran out of background time restarted
from the beginning on the next attempt, so on some phones it never completed at all and days simply
refused to compute. It now runs where it can finish, and a pass that is owed is recorded durably so a
process killed mid-way leaves evidence the next one can read.

Diagnostics that name the pass (#1556, #1559). Every re-score now says what triggered it and whether
anything actually changed, and the cache ratio is counted honestly. An active trace no longer disables
the reuse cache it was meant to observe (#1575).

Hardware gets its time back

The Oura ring is handed out of daytime mode (#1526, #1550, thanks @pipiche38). The 15-second
keep-alive held the ring in live-HR daytime mode whenever the app was not on screen — which blocks the
ring's own overnight sleep suite. NOOP now suspends the re-engage and actively disables the mode, on
teardown as well as on suspend. Measured against the ring's own output across eleven nights.

The bond loop can escape while backgrounded (#1544, thanks @justinjor-bit). A pause with no
background escape cost a full night of banked data; it now has one.

Steps calibration asks the right straps (#1579, #1581, #1582, thanks @kavemang). A WHOOP 5 no longer
sees a prompt that cannot apply to it, and a blank Steps tile routes to calibration instead of nothing.

Sleep and Health Connect

The night's heart-rate line, in Classic (#1552, thanks @bartmuskala). The card that was missing its
chart has it. The stage breakdown is ramp-aware and the redundant, mis-ordered legend is gone (#1551).

VO₂max flows to Health Connect (#1553, #1554). NOOP already computed it; it now exports it, and
existing installs are asked once for the permission rather than silently lacking it.

Smaller things that were wrong

• Pause and discard a live workout (#1533, thanks @bhelm), and the SDNN index ported to Android (#1535).
• Back from More returns to More (#1571, thanks @SpurgtBror), not to Today.
• No horizontal bounce on iOS (#1532, thanks @evoveotech), including the four ScrollViews the first sweep missed (#1549).
• Home is localized on both platforms (#1490, thanks @bhelm).
• PPG burst boundaries survive decoding (#1583, thanks @kvnloo).
• A WHOOP 5/MG no longer logs a clock warning it cannot act on (#1609), and no longer derives a clock offset from how long it went unworn.
• The phone smart alarm can skip chosen days (#1612) — a weekend off without turning the alarm off and having to remember to turn it back on.

Thanks

Thanks to @anwrgo6000-oss, @bartmuskala, @bhelm, @Dessalines39394, @evoveotech, @justinjor-bit,
@kavemang, @kvnloo, @mailingjash, @pipiche38, @SpurgtBror and @vishk23 — for the pull requests above and
for the reports behind them. A good bug report with a strap log attached is often the harder half, and
several of the fixes in this release exist because someone took the time to capture one.

• Sleep: give Android's Classic view the night's heart-rate line in #1552
• Health Connect: export VO₂ max, which NOOP already computes in #1553

NOOP v10.5.0

A release about seeing your training as a shape over time, getting numbers that used to need a tape
measure, and — most of all — your phone doing far less work to tell you the same things.

Training load

CTL, ATL and form (#1423, #1425). NOOP now models chronic and acute training load and the balance
between them, and draws all three on a Trends card. Fitness accumulates slowly, fatigue quickly, and the
gap between them is what tells you whether a hard block is building you up or digging a hole. Computed
on-device from the strain you already have; no new data is collected.

Sleep-versus-wake heart rate (#1424). The contrast between your sleeping and waking heart rate,
surfaced as its own signal rather than buried inside recovery.

A VO₂max you can actually get

Estimated without a waist measurement (#1391, #1406, #1393). The previous estimate needed a waist
circumference many people never enter. If NOOP knows your resting heart rate, it can now use the Uth
heart-rate-ratio method from age and sex alone, and it names which method produced the figure. An
estimate that says how it was reached is worth more than one that doesn't.

Battery

Stop re-scoring days that haven't changed (#1005, #1395, #1396, #1402). NOOP re-analysed a rolling
window every fifteen minutes, including days whose data had not moved since the last pass. A per-day
reuse cache now skips that work, on both WHOOP 4.0 and 5.0/MG. This was the largest background drain on
Android and it was reported, measured and chased down with logs by @bartmuskala.

Low refresh, and Power saving where you can find it (#1430, #1431). A sub-option syncs hourly at any
charge instead of every fifteen minutes — fewer reconnections is the biggest saving on a WHOOP 4.0 — and
Power saving moved into More, with the battery threshold now reaching 35%.

Fewer diagnostics running forever. Shadow instrumentation from the R-R over-count investigation was
doing six sorts of a night's beats per night, on every affected strap, four times an hour. Two
measurements that had finished their job were retired, and what replaced them costs one pass.

Apple Health, and your ring

Automatic Apple Health write-back (#1432, thanks @MikaSchultes). Workouts can flow back into Apple
Health without a manual export.

Hourly step import (#1429). iPhone steps arrive hour by hour, with a 90-day backfill, instead of one
lump per day.

More of the Oura ring decoded, and read honestly (thanks @pipiche38). The ring's own breath rate is
decoded and shown as instrumentation rather than scored (#1384, #1450); its step features are decoded as
Tier-B instrumentation (#1359); the skin-temperature "worn" gate now allows for a ring whose heart-rate
and temperature sensors run on independent clocks, which was blanking the card entirely (#1467); and the
Rhythm view says "no data" outright on hardware that cannot produce the reading, instead of showing an
empty chart (#1360).

Honesty and accuracy

A large part of this release is numbers that were quietly wrong, or quietly guessed:

• A completed sync no longer reports itself as interrupted (#1466). A WHOOP 4.0 routinely ends a
  full night's offload on an idle timeout; NOOP called that "sync interrupted" even when the whole night
  had landed.
• Diagnostic exports report the strap that actually connected (#1451, #1464). Two logs from WHOOP 5
  straps were headed "WHOOP 4.0", and on Apple the header had never reported a model at all.
• Battery percent refreshes twice as fast while charging, because that is the one time the number
  moves while you are watching it.
• The strap reconnect survives suspension (#1421), and a 5.0/MG that does serve history no longer
  thrashes its link every two minutes (#1414, thanks @justinjor-bit).
• Re-scoring no longer silently skips Oura, watch and re-added straps (#1392, thanks @pipiche38).

Cross-platform correctness

@bhelm contributed roughly thirty fixes in this release, almost all of the same kind: places where
the Swift and Kotlin implementations of one calculation disagreed. Half-tie rounding in recovery traces,
FIT coordinates and connection durations; signed zero surviving a clamp; DST-spanning stress windows;
sleep-stage clipping; malformed UTF-8 in the Oura text decoders; JSON control characters in Android
backups; Unicode normalization of custom lab-marker keys. Individually small, collectively the reason
the two platforms produce the same numbers from the same bytes.

@vishk23 extended the golden decoder oracle past frame decode (#869) — and it immediately found four
places where a 32-bit narrowing on Kotlin would have silently discarded all history from 2038, or today
on a strap with a future-dated clock.

@terry-zeng1134 fixed the AltStore manifest's declared permissions (#1388), and @Duzafizzl built
out the Breathe protocol catalog with holds, session lengths and translations (#1390).

Thanks

To @bhelm, @pipiche38, @vishk23, @MikaSchultes, @Duzafizzl and @terry-zeng1134
for the code; and to @bartmuskala, @justinjor-bit and @pipiche38 for reports carrying logs,
screenshots and measurements — several of which found bugs no test was going to catch.

And a belated thank-you to @gdorgian (#1366), @riebschlaegerstar-sys (#1361) and
@pilleuspulcher-blip (#159), whose reports were fixed in v10.1.0 but went uncredited in that
release's notes.
