Note: The Apple Watch integration is available on NC° app version 5.1.0 (or higher) and iPhones with iOS16 (or higher).
If you’re trying to connect your Apple Watch to Natural Cycles for the first time, this article will help.
Before sleeping each night:
Wear your Apple Watch on your wrist.
Tip: You may get more stable readings if you wear your watch on the inner wrist of your non-dominant hand (we recommend switching to the inner wrist at the start of a new cycle). Make sure the fit is not too loose or tight, and choose a band you find most comfortable.
- Make sure to charge your watch to at least 30%
- Ensure Sleep Focus is ON while you sleep and enabled for at least 4 hours each night (learn more here)
When you wake up:
- Turn off Sleep Focus (either manually or automatically via a set Sleep Schedule)
- Unlock your phone
- The temperature data collected by the Apple Watch should then automatically sync to the NC° app!
Natural Cycles will notify you that the sync was successful, so make sure you have notifications enabled (top menu > Settings > Notifications).
What does the timestamp under my temperature mean?
The timestamp shown under your temperature reflects when your Sleep Focus turned off and your temperature was added to Apple Health.
Once the temperature from your Apple Watch has synced to the NC° app, you will see your updated fertility status for the day on the Today page of the Natural Cycles app.
It’s important to ensure that your latest temperature data syncs and saves before you check your fertility status for the day, as the new data for today may update your daily fertility status.
