Google will close the third-party Fitbit smartwatch ecosystem on November 28, 2026, according to Gadgets & Wearables and Notebookcheck. After that date, the Fitbit App Gallery will carry only apps and clock faces made by Fitbit and Google.

Developers face the same deadline: they will no longer be able to upload new apps and clock faces or push updates to existing ones. The change covers the Sense, Sense 2, Versa, Versa 2, Versa 3, Versa 4 and Versa Lite, along with the recalled Fitbit Ionic.

The surprising part is not that anything stops working on the day itself — already-installed third-party apps and clock faces will keep functioning.

The catch, as Gadgets & Wearables stresses, is that anything deleted cannot be reinstalled, and a factory reset wipes access permanently because the gallery will no longer serve the software.

That makes the next two weeks critical: Sense and Versa watches can hold up to five saved clock faces, so owners of a favorite third-party design should leave it alone.

Notebookcheck reports Google has also asked owners to update to version 5.12 of the Google Health app, which replaced the Fitbit app in May.

The App Gallery was never the size of Apple's App Store or Wear OS, but Gadgets & Wearables recalls that it once made Fitbit's smartwatches feel genuinely expandable, with apps such as Strava, Starbucks, Uber, barcode tools and various utilities.

The writing has been on the wall for years: Google shifted its serious smartwatch ambitions to Pixel Watch and Wear OS, and Sense 2 and Versa 4 launched in 2022 without third-party app support at all, retaining only third-party clock faces — a door now closing as well.

Notebookcheck notes Google gave no reason for the change on its help page, but in 2024 the company already removed third-party apps for users in the European Economic Area, citing regulatory requirements.

Nothing suddenly breaks on November 28, but an expiry mechanism is now built into every third-party app and clock face: delete one, reset the watch or eventually replace the device, and it is gone for good.

Older Sense and Versa models lose the most, since they supported proper third-party apps, while Sense 2 and Versa 4 owners lose only outside clock faces.

There is an odd commercial footnote — Notebookcheck points out that Google still sells both the Sense 2 and Versa 4, discounted in its Black Friday sale from November 19, nine days before the cutoff, at $199.95 and $159.95 respectively.

The move completes Fitbit's retreat from smartwatch software toward simpler health and fitness hardware.
