Google Fit vs Google Health vs Health Connect

No, and conflating them is the biggest source of confusion in this search. Google Fit is Google’s older fitness app and developer APIs, which Google has been winding down since 2024, when it stopped onboarding new Fit API developers. Google Health is the current product, the app Fitbit became in May 2026. They come from different eras of Google’s health strategy, not two names for the same thing.

Yes. In May 2026 Google replaced the Fitbit app with the Google Health app for existing users; most accounts updated automatically between May 19 and May 26, and a Google Account is now required to sign in. Fitbit devices themselves did not change, only the app and account layer on top of them. Google’s own Help Center at support.google.com/googlehealth covers the transition in detail.

No. Google Health is a consumer app, the one your Fitbit data lives in now. Health Connect is a different layer: the on-device connector on Android that lets separate health and fitness apps share data with each other. Google Health can connect through Health Connect the same way other apps do, but the two are not interchangeable, and Google documents them as separate products with separate Help Center sections.

No. Your Fitbit device keeps tracking and syncing to the Google Health app regardless. What actually ends on September 30, 2026 is the legacy Fitbit Web API that third-party apps and integrations used to read your data, because those OAuth tokens do not carry over automatically. If you connect Fitbit data to an outside app or coach, that connection needs to re-authorize through the new Google Health API before the cutoff or it stops syncing, but the device and the Google Health app itself are unaffected.

Google Fit is an app you open, and it is on its way out. Health Connect is the hub apps share data through, and it is the standard Google now points developers toward as Fit is retired. One was a destination; the other is plumbing that keeps working even after the destination changes.

All three keep data on your device and gate sharing behind permission prompts. Health Connect’s entire job is per-app, per-data-type permission control, so it is the most granular of the three by design. Google Health, like any app, requests permission through Health Connect or its own settings when it wants to read or write. The privacy question comes down less to which product you use and more to which apps you have actually granted access.

Wellness Project reads Health Connect directly on Android, so anything flowing through that hub, including Google Health and Google Fit data, lands in your unified record. You do not connect to three separate things; you connect Health Connect once and the coaches read across whatever has synced into it.
