How to use Calmgraph and frequently asked questions
My score isn't showing
Add a 1-tap check-in (5 levels) from "Check in" on Home to see today's score. If you've connected Apple Watch, your score is computed once HRV and other data reaches your device (this can take a while depending on how you wear the Watch).
It says "Calibrating"
Your score is measured against your personal baseline. The first 14 days are a calibration period shown as provisional values. It grows more accurate the more you log.
Can I use it without an Apple Watch?
Yes. With subjective 1-tap check-ins alone, you get the full experience — score, tags, timeline, and weekly insight.
I want to change Health permissions
Change the read items anytime in iOS under Settings > Privacy & Security > Health > Calmgraph.
Restore a purchase / I got a new device
Tap "Restore purchase" in the Settings tab or the paywall. On the same Apple ID it restores with no extra charge. Because it's a one-time purchase, there is no subscription to cancel.
Is my data safe?
All data is stored only on your device — nothing is sent off-device, shared with third parties, or used for advertising. See the Privacy Policy for details.

About the Android version
The Android version supports Android 9.0 and later. It is being prepared for Google Play and cannot be downloaded yet.
To move to a new phone, export a backup from inside the app and import it on the new device. Cloud backup and device-to-device transfer are both disabled in the Android version, so nothing carries over automatically.
For questions, use the contact address below. Telling us whether you are on the iOS or the Android version gets you a faster answer.
