(Pocket-lint) – Natural Cycles has announced a partnership with Oura, which could be a game-changer for users of the FDA-cleared birth control app if they also use an Oura ring.

The Natural Cycles app analyzes hormone-related temperature patterns, along with other key fertility indicators, to determine if a woman is fertile or not, to help her plan or prevent pregnancy.

Users get red (fertile) or green (non-fertile) days if they have chosen pregnancy prevention mode, and vice versa if they have chosen pregnancy planning mode. In order for the algorithm to determine these days for each user, you must enter your temperature in the application for as many days as possible in the month, which you must take using an oral thermometer upon waking. It is also necessary to take into account the different rhythms of sleep or alcohol, and to give the application the correct information.

The partnership with Oura – the company behind the Oura Ring, a smart ring that provides personalized health data, insights and daily guidance – greatly simplifies this process. Instead of having to take their temperature manually, Oura Ring users who switch to Oura Mode in the Natural Cycles app will do so automatically.

According to Natural Cycles: “Oura Ring temperature sensors generate 1,440 data points each day, and are validated to measure temperature changes with an accuracy of 0.13°C (0.234°F).

“In addition to temperature trend data, the Natural Cycles algorithm uses heart rate data from the Oura Ring to account for nights with elevated heart rates that may be due to lifestyle changes, such as heavy alcohol consumption, rather than menstrual cycle changes.”

The Oura Ring also tracks and analyzes sleep quality and it has features like daytime heart rate, training heart rate and automatic activity detection to assess movement and rest time. These personalized health metrics are then summarized into sleep, activity, and readiness scores.

While the benefits only apply to those who use the Natural Cycles app and have an Oura ring, this is great news for those who want to use a hormone-free method of birth control and don’t have the chore of entering temperature data every morning to get the best results.
