Our integration with Apple Health enables you to import fertility data into Natural Cycles from the Apple Health app, in case you were tracking your fertility before in a different app and don’t want to start from scratch with Natural Cycles. You can also back up your Natural Cycles data in the Apple Health app.
This functionality is only supported on iOS devices and not on Android.
What data can I sync between Natural Cycle and Apple Health?
When syncing data between Natural Cycles and Apple Health, you are able to import or export the following types of data:
- Temperature*
- Period & period flow
- Spotting
- Cervical mucus
- LH tests
- Sex
*If you’re using Natural Cycles with an Oura Ring, temperature data will not be imported from Apple Health to the NC° app. Please also note that temperature data from the Apple Watch will not transfer to Natural Cycles. At this time, you can only use Natural Cycles with a basal thermometer or the Oura Ring.
How to set up the Apple Health integration
To enable syncing between Natural Cycles and the Apple Health app, follow the steps below:
- Go to the top menu in the Natural Cycles app > Settings > Integrations
- Under Apple Health cycle data, select if you want to export and/or import data
- Confirm in the popup that you want to sync your Apple Health data with Natural Cycles.
Once the integration is set up, your data will sync automatically to or from Apple Health (depending on what you have selected) every time you open the Natural Cycles app.
How to turn off syncing between Natural Cycles and Apple Health
If you don’t want to sync your data between Natural Cycles and Apple Health anymore, you can turn the integration off at any time by following these steps:
- Go to the top menu in the Natural Cycles app > Settings > Integrations
- Under Apple Health cycle data, turn the sliders next to Export and Import off
Please note that any data that you have already synced will still be there. If you want to remove your synced data, you have to go to your Add data page for each day and remove the data.
What to do if you can’t sync with Apple Health
If your data is not syncing, it might be because Natural Cycles doesn’t have permission to access your Apple Health data.
To ensure that you have these permissions enabled:
- Open the Settings app on your device
- Go to Privacy > Health > Natural Cycles
- Select “Turn on all” permissions
- Open the Natural Cycles app and go to the top menu > Settings > Integrations
- Make sure that you’ve selected if you want to import and/or export data
If you’re still struggling to sync Natural Cycles to Apple Health, please check if any of the following scenarios apply:
- Were you previously using hormonal birth control? Please note that it’s not possible to sync data from when you were using hormones.
- Are you trying to import temperature data?
- Please check to see if any of the temperatures are below 32°C or 89.6°F, as this will prevent the algorithm from importing data. If you do have temperatures below 32°C or 89.6°F, delete those from Apple Health and then try to sync again.
- Kindly note that it is not possible to sync temperatures from the Apple Watch.
- If you’re using Natural Cycles with an Oura Ring, you’re not able to import temperature data from Apple Health.
If you still need help, please contact our support team and they will look into this for you. When you reach out to us, please let us know which data you are expecting to sync with Apple Health. It would also be helpful if you could include screenshots of the data that you are looking to import or export, and any error messages you may get.
