Frequently Asked Questions

How do I tell a Fitbit Ace apart from a Fitbit Inspire?

Both trackers share a similar slim, pill-shaped case, but the Ace pairs with a child's Fitbit account and is sized for smaller wrists, while the Inspire is the adult version. Checking the device name under your profile in the Fitbit app confirms which one you own. Kids' trackers need bands from the Fitbit Ace collection, and adult trackers need the Fitbit Inspire collection.

Do Fitbit Versa 4 bands fit the Sense 2?

Yes - the Versa 4 and Sense 2 share the same case and clasp, so any band made for one fits the other. They were released together and use an identical quick-release mechanism, which is why bands for both are listed as a single combined collection. Shop the Fitbit Versa 4 and Sense 2 collection without needing to work out which tracker you actually own.

Will a Fitbit Versa 3 band fit a Versa 4?

No. Fitbit changed the attachment mechanism between generations, so Versa 3 and Versa 4 bands aren't cross-compatible. The Versa 3 shares its fitting with the original Sense, while the Versa 4 shares its fitting with the Sense 2. Check your exact model before ordering - the Fitbit Versa 3 and Sense collection and the Fitbit Versa 4 and Sense 2 collection each stock the correct match.

Why don't Fitbit bands come in a standard mm size like other watches?

Fitbit uses its own proprietary quick-release clips instead of the universal spring-bar lug system found on Garmin, Samsung or Apple watches, so there's no millimetre width to measure. Each Fitbit family - Charge, Versa/Sense, Inspire and Ace - has its own connector, which is why bands are sold by model name rather than by size.

How do I tell a Fitbit Sense apart from a Fitbit Sense 2?

Both watches share the same square case, so the easiest way to tell them apart is by band fitting: the original Sense matches the Versa 3, and the Sense 2 matches the Versa 4. Confirming the device name in the Fitbit app tells you which you own - then the Fitbit Versa 3 and Sense collection or the Fitbit Versa 4 and Sense 2 collection has the right bands.
