How to Sync Fitbit to Apple Health on Your iPhone

Fitbit and Apple Health can work together, but they need some help from a third-party app. Until Fitbit is ready to approve direct syncing with Apple Health, third-party apps need to be used to sync the Fitbit app with the Apple Health app. Our favorite app is Sync Solver for Fitbit ($4.99). To connect Fitbit to Apple Health:

1. From the App Store, download the Sync Solver for Fitbit app.

2. Open the Sync Solver app and tap Sync Now.
3. A message will pop up; tap Continue.

4. Your Health app will open; tap Turn All Categories On.
5. Next, the app will redirect you to Fitbit.com.
6. Log into your account.

7. Sync Solver will ask permission for info from Fitbit; tap Allow.
8. Your iPhone will want to open Sync Solver; tap Open.

9. Your Fitbit info will then sync with Sync Solver.

10. Any time you want to update your Health app information with your Fitbit's data, return to Sync Solver and tap Sync Now.

11. Sync your Fitbit with the Sync Solver app.

Can you sync Fitbit Charge 3 to iPhone? Yes! These steps should work for any model of Fitbit and several others.

Pro Tip: Syncing your Fitbit and Apple Health is not the same as learning how to pair your Fitbit with your phone. This is done using the Fitbit app by tapping Set Up a Device from the account page.
