New Fitbit Air details how it compares to Whoop — and how it actually works

What you need to know

• Fitbit Air is much slimmer and lighter than Whoop while still promising up to a week of battery life.
• The tracker uses LED light patterns and double-tap gestures to show battery status and dismiss alarms.
• Fitbit Air costs $99 and pre-orders before May 25 also include a $35 Google Store credit.

Last week, Google officially revealed the Fitbit Air, its direct competitor to Whoop, and now, ahead of its availability later this month, more details about its size, design, and gestures have surfaced.

At first glance, the Fitbit Air looks similar to other screenless fitness trackers, with just a fabric band wrapping around the wrist and the tracker sitting underneath. Demo units are now live at various Google Store locations, and a Reddit user has shared photos comparing the Fitbit Air side by side with a Whoop band.

From the image, the Fitbit Air looks noticeably slimmer, almost half the size of the Whoop. The photos also give us a better look at the Fitbit Air's Performance Loop band in real life. Considering Google is claiming up to a week of battery life in a much slimmer form factor, things are looking pretty promising so far.

It's also worth noting that the Fitbit Air weighs just 12g, making it lighter than the Whoop, which should help with comfort during all-day wear.

In addition to that, new details shared by 9to5Google reveal that the left side of the tracker includes a small status light. Even though the tracker itself remains hidden beneath the band, the band has a cutout so the LED can shine through. You'll need to align the band correctly with the LED for it to remain visible.

The LED also uses different patterns to indicate various states. For example, it pulses white while charging and flashes red when the battery is running low. A fast blinking white light indicates a firmware update, while a solid red light signals a critically low battery.

You can also double-tap the Fitbit Air to check its battery status. A white light means the battery is between 20% and 100%, while a red light means it's below 20%. No light means the battery is completely drained. The double-tap gesture can also be used to dismiss alarms.

The Fitbit Air is currently available for pre-order for $99, with wider availability and shipping starting May 26, 2026. Google is also offering a $35 Google Store credit if you pre-order before May 25, which you can use toward accessories like extra bands.
