Note: the only wearable devices that are compatible with Natural Cycles are the Oura Ring and the Apple Watch. Learn more here.
When using Natural Cycles with your Oura Ring or Apple Watch, you won’t be able to log any temperature data manually. This is to prevent measuring with two devices at the same time – we write more about this here.
If you decide you want to switch from using a thermometer to using the Oura Ring/Apple Watch or vice versa, you can do this in your app by going to the top menu > My Device > Change device.
Before switching devices, there are a few things to keep in mind:
- For a better experience, we recommend only switching measuring devices at the start of a new cycle.
- Please keep in mind that you should avoid switching measuring devices too often not only to stay in the habit of measuring with your chosen device, but also because this may otherwise delay ovulation detection and cause more Red Days (NC° Birth Control) or Brown Days (NC° Plan Pregnancy).
- You also should never use two measuring devices simultaneously (either two of the same kind or two different kinds). You can read more about this here.
