Sleep & HRV recovery score
RecoverySync
RecoverySync analyzes your HRV, resting heart rate, and sleep to deliver a single daily recovery score — every morning.
One score. Three signals.
Your recovery score is calculated from the sleep, HRV and resting heart rate your wearable writes to Apple Health — Apple Watch, for example.
Built different.

About the Android version
On Android, RecoverySync reads active calories burned, heart rate, heart rate variability, resting heart rate and sleep from Health Connect, so it works with the data your watch or health app already records there.
The Android version of RecoverySync is available on Google Play. It supports Android 9.0 and later.
Both implementations are checked against the same verification data so that the Android build calculates and judges exactly as the iOS one does. Storage and backup behaviour is described in the privacy policy.
For questions about the Android version, see the support page.
