We’ve integrated the Natural Cycles app with compatible Garmin wearables to bring you a whole new way to measure! Garmin measures while you sleep, then our algorithm analyzes the temperature data, providing unique insights only available in your Natural Cycles app.
Garmin is not FDA-cleared nor intended to be used as birth control, so it's essential to open the NC° app every day to check your fertility status.
How do select Garmin wearables work with NC°?
- Wear your compatible Garmin wearable while you sleep
- Wake up and sync your Garmin with the Garmin Connect app
- Wait for the push notification from your NC° app letting you know your fertility status is ready
- Learn your daily fertility status!
What data is shared between Garmin and Natural Cycles?
Garmin will only share sleep data with Natural Cycles (which includes temperature data, heart rate, sleep length, and sleep stages). The Natural Cycles app will not get any period or cycle data from the Garmin App.
For data protection reasons, Natural Cycles does not share any sensitive data with Garmin. The partnership is a one-way integration, which means that any data you log on the Natural Cycles app will not sync with Garmin.
This is a one-way integration, which means that any data you log on the Natural Cycles app will not sync back with the Garmin 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 Garmin’s team to help resolve the problem. For more details, you can view our Privacy Policy.
Where can I purchase a Garmin wearable?
You can purchase a Garmin wearable through the app's top menu > Buy Extra Supplies. New users can claim exclusive savings on a new Garmin wearable, plus 10% off the NC° Annual Plan.
How to connect your Garmin wearable to the Natural Cycles app
As a new user
- Sign up for Natural Cycles and choose Garmin as your measuring device.
- Log into the Natural Cycles app. Follow the in-app instructions to connect your Garmin account. Enable permissions for heart rate and wrist temperature data when asked.
- Sleep wearing your Garmin wearable overnight. Open Garmin Connect in the morning to sync your data. Your temperature data is then sent to the Natural Cycles app, and our algorithm transforms this data into your daily fertility status. Open the Natural Cycles app to see your daily fertility status.
⚠️ Important: Always check the NC° app for your fertility status. Garmin 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. Garmin Connect does not use our regulated algorithm and should never be used for birth control.
As an existing user
You can change your measuring device at any time by going to the app’s top menu > My device > Switch device.
Please note that we recommend only switching measuring devices at the start of a new cycle. Check out the article How to switch measuring devices to learn more.
