- Oura is working on a new feature that could help users track their fertility window.
- The feature will rely on body temperature data to deliver fertility predictions.
- It’s not immediately clear whether the feature will be part of the Natural Cycles integration.
In a bid to make its smart rings more appealing than Samsung’s new Galaxy Ring, Oura is working on a host of new features. We recently shared details about two in-development features that will give users better heart rate insights and allow them to log their meals. Now, we’ve spotted evidence of another upcoming feature that will provide users with fertility predictions.
Oura currently relies on the Natural Cycles app for menstrual cycle tracking. This feature utilizes body temperature data collected by the ring to track users’ menstrual cycles and provide helpful insights. However, it requires a separate subscription for the Natural Cycles app.
Evidence spotted in the latest Oura app update (version 5.3.5) suggests that the app could gain a native alternative soon, but it may only offer fertility predictions. The in-development feature will also use body temperature data collected by the ring.
The feature will require users to wear their Oura Ring for at least 60 nights and log their most recent period start date to get a fertility prediction. In cases where a user has previous Cycle Insights data from Natural Cycles, the upcoming feature may utilize that data to offer a prediction.
Since the strings state that the Fertile Window feature can utilize Cycle Insights data, there is a chance that it may just be part of the Natural Cycles integration. In that case, users will need a Natural Cycles subscription to use the feature. We’ll have to wait until the rollout to know whether or not the Fertile Window feature will require a separate subscription.
