Frequently Asked Questions
Which Garmin watches are compatible?
Most Garmin watches from 2017 onwards with Connect IQ 3.1 or higher. That's 8+ years of compatible devices. Works best with touchscreen devices but supports all compatible watches. Full compatibility list available in the Connect IQ app store.
How much does Untether cost?
14-day free trial, then $4.99 one-time purchase to continue using. No subscriptions, no recurring fees. Requires a Google Gemini API key - normal usage fits within their generous free tier. Paid plans available if you exceed free tier limits.
Does this work without my phone?
Yes! Untether works standalone over Wi-Fi without your phone - the first AI assistant on Connect IQ with true standalone capability. By default, it uses Bluetooth when your phone is nearby for convenience.
What about my data privacy?
Your API key is stored locally on your watch only. Untether BYOK has no backend servers - we never see your queries or responses. Your data goes directly to Google Gemini using your own credentials.
Can I use it during activities?
Best used before or after activities. During workouts, your watch is focused on tracking performance.
What if I don't know what an API key is?
An affordable subscription version (no API key required) is coming soon. Join the waitlist to be notified when it launches ($1.99/month).
For now, getting a Google Gemini API key is free and takes just a few minutes to set up.
Can it analyze my past workouts?
No. Connect IQ API limitations prevent access to past workout data. Untether can access live sensor data and your fitness profile (like VO2 max and training zones), but not workout history. It's designed for quick questions throughout your day, not post-workout analysis. For workout insights, use Garmin Connect or your watch's native fitness features.
