Oura Ring is one of the integrated wearable devices you can use with Natural Cycles. It sends Natural Cycles temperature data, which the NC° Algorithm uses to calculate your daily fertility status in the Natural Cycles app!
Natural Cycles can be used with any Oura Ring model (Gen 2 and later).
How does the Oura Ring work with Natural Cycles?
- Wear your Oura Ring while you sleep
- Sync your ring with the Oura App when you wake up

⚠️ Important: Always check the NC° app for your fertility status. Oura Ring syncs your body temperature data with the Natural Cycles app — our algorithm then analyzes this alongside other cycle variables, which may cause your ovulation and temperature data to look different in each app. The Oura App does not use our regulated algorithm and should never be used for birth control.
What data is shared between Natural Cycles and the Oura Ring?
Oura will only share sleep data with Natural Cycles (which includes temperature trends, HR, sleep length, and sleep stages). The Natural Cycles app will not get any period or cycle data from the Oura App.
For data protection reasons, Natural Cycles does not share any sensitive data with Oura. This is a one-way integration, which means that any data you log on the Natural Cycles app will not sync back with the Oura App. Always refer to the NC° app for a daily fertility status.
However, if you contact our Customer Care Team to troubleshoot a technical issue with the integration, we may securely share relevant data with Oura’s team to help resolve the problem. For more details, you can view our Privacy Policy.
If you are an iPhone user, you can use the Apple Health app to sync your period data between the Oura App and the NC° app. You can learn more about this here: How to sync with Apple Health
How does using Natural Cycles with an Oura Ring differ from an oral thermometer?
The biggest difference between using an Oura Ring and an oral thermometer is that you don’t have to remember to measure your temperature every morning because you wear the ring overnight.
Just make sure that you wear your (charged) ring every night. In the morning, sync your Oura Ring with the NC° app, check your fertility status, and that’s it!
No matter which compatible device you use, the effectiveness of Natural Cycles remains the same. Natural Cycles is 93% effective with typical use and 98% effective with perfect use.
Please keep in mind that using the Oura Ring is not the same as measuring orally with a thermometer, and temperature data should not be compared to measurements from an oral thermometer or other devices. We write more about this here: Why different measuring devices give different temperatures
