The fit52 app syncs directly with Apple Health, and unfortunately at present Fitbit does not offer a direct integration with Apple Health.
There are some third-party apps available in the App Store that will allow you to sync Fitbit with Apple Health.
If you are connected with Apple Health, you can sync your data with fit52 following these steps:
- Open fit52. Navigate to Profile (located bottom-right corner of the screen).
- Tap Settings (Gear icon located top-right corner of the screen).
- Tap Integrations.
- Turn on Apple Health.
