Oura Ring Gen 3 Health Connect sync guide 2026
Oura Ring Gen 3 established finger-based health tracking as a serious alternative to wrist-worn wearables. The Gen 3 writes sleep stages, HRV, SpO2, and skin temperature to Health Connect on Android, allowing FitMesh to surface Oura sleep data alongside data from other devices. The finger-based optical sensor provides higher HRV measurement accuracy than wrist sensors, making Oura Ring Gen 3 one of the most reliable overnight HRV sources available via Health Connect.

Frequently asked questions
Does Oura Ring Gen 3 write Readiness Score to Health Connect?+
Readiness Score is Oura-proprietary and stays inside the Oura app. However, the underlying data that feeds into Readiness (HRV, sleep stages, SpO2, skin temperature) all write to Health Connect and are readable by FitMesh.
Is Oura Ring Gen 3 or Gen 4 better for Health Connect data?+
Both Gen 3 and Gen 4 write the same data types to Health Connect. Gen 4 has improved sensor hardware for better measurement accuracy, but the Health Connect data schema is identical. If you already have Gen 3, there is no reason to upgrade specifically for Health Connect use.
Can I use Oura Ring Gen 3 without an Oura subscription for Health Connect?+
Yes. Oura Ring writes data to Health Connect regardless of subscription status. The Readiness explanations and trends inside the Oura app require a subscription, but FitMesh reads the underlying health data from Health Connect for free.
