Show HN: Free biological-age calculator from standard bloodwork
longevity-tools.comHi HN — first-time poster here!
I’m Zsolt. I build blood-interpretation tools used by longevity clinics and try to make everything public.
I built this biological-age calculator with help from one of the study authors. It is based on Bortz Blood Age model, which is currently the best public model on standard lab tests (beats PhenoAge). Trained on actual mortality (not chronological age) and validated on 300k+ participants. Validated on similar dataset.
On top of calculating bioage, it shows biggest levers to focus on.
There a video explainer about the calculator: https://www.youtube.com/watch?v=2VHIfouvcYE
It is 100% free - no email or sign up required 100% private - runs on client side, nothing is sent to server and I have no 3rd party scripts on the site, not even analytics.
