Oura Ring and Natural Cycles announce fertility tracking integration

Fertility tracking app Natural Cycles is now integrated with the Oura Ring health tracking wearable. Natural Cycles claims to be the first FDA-cleared and CE-marked birth control app, with a 93% effectiveness rate. The app requires you to measure and manually record your temperature daily and then uses an algorithm based on hormone-driven temperature patterns to determine your fertility status.

Through the partnership, you can sync temperature trend data automatically between your Oura smart ring and Natural Cycles app. The ring will use its temperature sensors to measure while you sleep, removing the daily manual task and ensuring you do not accidentally miss a day. The Oura Ring’s temperature sensors already generate 1,440 data points each day. These measurements are validated and can record fluctuations as small as 0.13°C (0.23°F), according to Oura.

Natural Cycles can also use the heart rate data collected by the Oura Ring to account for nights where your temperature may be elevated for reasons other than hormones, such as alcohol consumption. You can activate the integration by switching to Oura Mode in the Natural Cycles app. The integration is one way, with Oura sharing temperature, heart rate, sleep length and sleep stage data.

Another partnership announced by Oura recently was with Strava. The two-way connection allows exercise logged by Strava to be shared to your Oura app and considered for your health score. Plus, users can share Oura-generated insights with their Strava followers.
