If you prefer dark mode on your phone, the great news is that Natural Cycles also gives you the option to use the app in dark mode!
To enable dark mode in the app, tap the top menu > Settings > Appearance > select Dark mode.
You can revert to the light mode at any time.
Please note that light mode is the default setting in the app; when you create your account, your app will be in light mode until you change it in the Appearance settings.
If you select System Preferences from the Appearance settings, the Natural Cycles app will automatically match your device’s settings — if your device is in light mode, the app will be in light mode and if your device is in dark mode, the app will be in dark mode. If you make changes to your device’s appearance settings, these changes will also be applied to the Natural Cycles app.
