You can use your Oura Ring with Natural Cycles (NC°), the first FDA-cleared birth control app. Oura Ring members can sync their temperature trend data collected overnight into the Natural Cycles app each morning, which will then be analyzed using Natural Cycle's algorithm to calculate daily fertility status.

Data Synced with Natural Cycles
Temperature trend data collected overnight from the Oura Ring will be synced to the NC° app every day to help calculate your fertility status within the Natural Cycles app. The temperature sensors in the Oura Ring generate 1,440 data points each day, and are validated to measure temperature changes as precisely as 0.13°C (0.23°F).
If you're a current Oura member but a new Natural Cycles user, only the temperatures recorded after the earliest period you entered in the NC° app will be used by the Natural Cycles algorithm. Note that this only applies if you indicated during setup that you haven't recently used hormonal birth control or been pregnant.
The NC° app doesn't receive any period data from your Oura App, so you always have to log your period directly in the NC° app. Natural Cycles also syncs with Apple Health.
If you're using both Oura and Natural Cycles, you may notice slight differences in predictions between the two apps. That’s because each uses its own proprietary model based on your temperature trend data. Natural Cycles’ FDA-cleared algorithm is specifically optimized for fertility tracking and birth control.
