Oura Ring 4 Health Connect sync guide 2026
Oura Ring 4 improved the optical sensor with 18 signal pathways (up from 8 in Gen 3) for more accurate heart rate and HRV measurements. It also introduced Smart Ring sizing for easier fitting. The Health Connect integration is identical to Gen 3: sleep stages, HRV, SpO2, skin temperature, and resting heart rate all write to Health Connect via the Oura app, and FitMesh reads them automatically.

자주 묻는 질문
Does Oura Ring 4 write better HRV data to Health Connect than Gen 3?+
Oura Ring 4 has a more accurate optical sensor which improves the underlying HRV measurement. The data written to Health Connect uses the same RMSSD format as Gen 3, so the structure is identical but the values may be more precise with Ring 4.
Does Oura Ring 4 work on Android without the Oura app?+
No. The Oura app is required to sync data from the ring to the phone. Once synced, the app writes to Health Connect. FitMesh then reads from Health Connect. You need the Oura app installed but do not need it open for FitMesh to read your data.
Is Oura Ring 4 compatible with Samsung phones for Health Connect?+
Yes. Oura Ring 4 works with any Android 9+ phone including Samsung devices. On Samsung phones with Samsung Health, FitMesh can read both Oura data from Health Connect and Samsung Health data from the Samsung Health integration simultaneously.
