Sleep tracking on Android
All your sleep data in one place, from any wearable
FitMesh reads sleep stages, HRV, and SpO2 from any device that writes to Health Connect: Galaxy Ring, Oura, Garmin, Polar, Galaxy Watch, and more.
Your sleep data is split across different apps depending on which device you use. Oura Ring, Garmin, Polar, Samsung Health, and Google Fit each store sleep data in their own silos. Health Connect changes this: it acts as a shared data layer on Android where all compatible devices write their sleep data, and any app can read it all in one place.
Sleep metrics FitMesh reads from Health Connect
- Sleep stages: light, deep, REM, and awake periods, from all compatible devices.
- HRV (overnight): nightly heart rate variability from rings and watches that measure it.
- SpO2: blood oxygen saturation measured during sleep.
- Respiratory rate: breaths per minute from devices that track it.
- Resting heart rate: nightly average.
- Skin temperature: deviation from baseline (Oura Ring, Samsung Galaxy Ring, some Garmin models).
- Sleep duration and timing: start time, end time, and total sleep across all devices.

Frequently asked questions
Do I need a subscription to track sleep with FitMesh?+
No. FitMesh reads your sleep data from Health Connect at no cost. Your wearable's app may require its own subscription for advanced features, but the sleep data in Health Connect is always accessible.
Which sleep metric is most important?+
HRV during sleep is the most useful recovery indicator. A higher overnight HRV means your body recovered well. Sleep stages (especially the amount of deep sleep) tell you about physical restoration. Track the trend over weeks, not a single night.
Can I see sleep data from two different devices in the same timeline?+
Yes. If both devices write sleep data to Health Connect, FitMesh shows both. You can filter by data source if you want to see only one device.
Does FitMesh store my sleep data on its servers?+
FitMesh Sync mirrors your Health Connect data to a personal cloud dashboard. Data is stored on EU servers and never sold or shared. You can delete your data at any time.
