On the trackers (Charge, Inspire, Luxe), use full-cover TPU film: their screens curve into the body and flat glass lifts. On the squarer Versa and Sense smartwatches, tempered glass fits. The Fitbit Air has no screen, so it needs nothing.

Why trackers reject glass
A Charge or Inspire screen is a small panel curving into a narrow body. Rigid glass can only sit on the flat centre, which leaves most of the display exposed and an edge for sleeves to catch. Full-cover TPU film stretches over the whole face and down the sides, which is both better coverage and less likely to peel.
Fitbits also take a particular kind of damage: they're worn during exercise, where the risk is scraping a gym machine or a doorframe rather than dropping the device. Film handles scratches; nothing on the market stops a hard knock on a tracker that size.
Fitting film on something this small
- Take the band off first if it detaches, so you can lay the body flat.
- Wipe with the alcohol wipe, then let it dry fully: sweat residue stops film bonding.
- Work from the centre outwards and expect to press the edges down for a few seconds each.
- Buy multipacks. At this size, film is cheap and the first attempt often goes crooked.
Questions people ask
Does the Fitbit Air need a screen protector?
No. It's a screenless tracker, so there's nothing to protect.
Can I put tempered glass on a Fitbit Charge?
Not well. The screen curves into the body, so glass covers only the middle. Full-cover film is the better fit.
