How to sync Fitbit with Apple Health in 2026, after the Google Health change
Updated 1 November 2026. Written by Minima Apps Ltd, the makers of Tandeo, so we mention Tandeo as one option. We try to be fair about the others.
What changed
Fitbit data now flows through Google Health, and developers reach it through the Google Health API. The older Fitbit web API that many apps used to read your data was turned off on 2 November 2026. Any app or connection that depended on the old service has to be rebuilt on the new one, and you usually have to sign in again with your Google account.
That is why people search for "Fitbit not syncing with Apple Health" or "Fitbit to Apple Health not working": a connection that worked last year may simply have stopped, through no fault of your phone or watch.
Does Fitbit or Google Health sync to Apple Health by itself?
As far as we know, no. Apple Health and Google Health are separate systems, and neither company's own app copies your data across to the other on its own. Check the current version of the Fitbit or Google Health app and Apple's Health app in case that changes. If you want your Fitbit steps, sleep, heart rate or workouts to appear in Apple Health, you need a third-party bridge.
Your options
1. A sync app that uses the Google Health API
Apps built on the new Google Health API can read your Fitbit data from Google and write it into Apple Health through HealthKit. Make sure the app you choose says it uses Google Health (not the retired Fitbit API), runs on your device rather than a server if privacy matters to you, and tells you plainly which data types it copies.
2. Export your data
You can download your data from Google (Google Takeout). This is a one-off archive for safekeeping or analysis. It is not an easy way to put historic data into Apple Health, and it does not keep the two in step.
3. Keep the two worlds separate
Many people simply use the Fitbit or Google Health app for Fitbit data and the Health app for everything else. That costs nothing, but your Apple Watch rings, iPhone steps and Fitbit data will not combine in one place.
Syncing with Tandeo
Tandeo is our app for this job. It is a two-way bridge between Google Health and Apple Health that runs on your iPhone or iPad.
- Connect Google Health. Sign in with the Google account your Fitbit data lives in and approve the data you want to share.
- Pick your data and direction. From Google Health to Apple Health: steps, distance, active energy, heart rate, resting heart rate, heart rate variability, blood oxygen, sleep with stages, weight, body fat and workouts. From Apple Health to Google Health: weight, body fat, workouts and sleep.
- Sync. Tap sync, or let Tandeo run in the background if you have Pro or Lifetime.
Free covers steps and sleep from Google Health to Apple Health with manual sync. Pro is $2.99 a month or $14.99 a year (the yearly plan has a 1-week free trial). Lifetime is a one-time $29.99. Syncing happens on your device, and Tandeo has no account and no servers receiving your health data. Coming soon to the App Store.
Why does Apple Health to Google Health only cover some data?
Google Health does not accept steps or heart rate data written by other apps, so those can only flow from Google Health into Apple Health. Weight, body fat, workouts and sleep can go both ways.
Will I get duplicate data?
If more than one app writes the same kind of data into Apple Health, for example steps from your iPhone and from a sync app, Apple Health combines sources using a priority list. You can reorder it in the Health app under the data type, then Data Sources & Access. Tandeo also tracks what it has already written in each direction so it does not copy the same record back and forth.
A note on background sync
On iOS, apps cannot sync continuously in the background. The system decides when background work runs, based on battery, connectivity and how often you use the app. Any sync app, ours included, can be delayed. Opening the app and syncing manually always works.
