Sync For Apple Health Fitbit is an iPhone application developed by Bickster LLC. This app allows you to upload your Apple Health data to your Fitbit account. After syncing, your fitness data can be viewed on the Fitbit app or Fitbit.com. You can sync up to 5 fields, including steps, weight, body fat percentage, sleep analysis, and water. The app features an auto-sync function, which automatically keeps your data up to date.

Users have praised the app's easy-to-use interface and the fact that it syncs automatically every day. However, the app has some limitations, such as Fitbit not allowing third-party apps or devices to compete in step challenges or share steps with community members. The app syncs up to 30 days of historical data and overwrites the last 30 days of step, weight, and BMI data in your Fitbit account when using this app for the first time.

Overall, Sync For Apple Health Fitbit is a great tool for those who use both Apple Health and Fitbit. The app is available for a fixed subscription price, which varies by country. If you encounter any issues or would like to request a new feature, you can contact or click the "App Support" button in the App Store.
