Fitbit Charge 6 gets new faces & gym support, other models see fixes

Fitbit has been unusually quiet in 2025. No new devices, barely a word from the team, and firmware updates have been few and far between. But now there’s finally something to talk about. Charge 6 gets fresh clock faces and broader gym equipment support and there are bug fixes to Versa 4, Sense 2 and Inspire 3.

Charge 6 gets new faces and gym upgrades

Firmware update 220.21 is rolling out now to Charge 6 owners, and while it won’t change how you use the tracker overnight, it does give the device a bit more character. The highlight is a trio of new clock faces: Axira, Geometric and Momentum. They’re built to show more data directly on the home screen and to let users jump into core stats without diving through layers of menus.

Also included in the update is a boost to how the Charge 6 connects with fitness equipment. The device could already share your real-time heart rate with some treadmills and bikes, but this update expands the list of compatible gear.

Versa 4, Sense 2 and Inspire 3 get bug fixes

The new firmware doesn’t stop with Charge 6. Fitbit has also slipped in some fixes for other models, including the Versa 4, Sense 2 and Inspire 3. These aren’t feature updates, and Fitbit hasn’t gone into detail, just noting that the changes are “general bug fixes and improvements.” Still, it’s the first firmware movement in a while for these devices, so it’s worth checking if your watch is ready to update.

So far there’s no sign of bigger changes to the UI or any other ground-breaking new features. That said, the fact that Fitbit is still pushing updates at all is mildly encouraging, especially in a year where the brand has said almost nothing.

We are still hopeful the Charge 7 might land soon. Perhaps at the tail end of August, ahead of IFA in Berlin. That will mark nearly two years since the Charge 6 was released. The company typically announces a new version every other year.
