A tracker with nothing to look at

Every Fitbit before this one had a display. The Air does not. There is a woven band, a sealed module about the size of a large watch clasp, and that is the object. Nothing lights up, nothing buzzes with a notification, and there is no way to check the time on it.

That sounds like a subtraction and it is meant to. A screen is the part of a wearable that pulls you back onto a device forty times a day. Take it away and the band does one job: it measures, all day and all night, and you look at the results when you decide to. Google is not the first to work this out, but it is the first to sell the idea at £85.

What it measures

Google says the Air tracks heart rate continuously, heart rate variability, blood oxygen, steps and sleep, and that it watches for the irregular rhythm associated with atrial fibrillation. Google also claims the sleep tracking is 15% more accurate than previous Fitbits, and adds a personalised circadian-rhythm reading on top of the usual stages.

Take the atrial fibrillation feature for what it is. It is a notification, not a diagnosis, and a wrist sensor is not a cardiologist. If it tells you something, that is a reason to speak to a GP, not a result to act on by yourself.

Battery, and what it costs to keep

Google quotes up to seven days. Tech Advisor's reviewer wore one from a Saturday to the following Saturday before it needed a full charge, so the claim holds up in ordinary use. The charger is proprietary, though, so an old Fitbit cable in a drawer will not help you.

The band works without a subscription. Google Health Premium sits on top at £7.99 a month and unlocks the AI coaching, and three months come in the box. After that it is a real recurring cost, so price the thing at £84.99 plus £96 a year if the coaching is the part you actually want.

What it does not do

No GPS, so a run is tracked by your phone or not at all. No NFC, so no contactless payments. No display, so no notifications, no timer, no time. Google does not publish a water-resistance depth for the Air on the UK listings and neither does Amazon, so treat it as fine in sweat and rain and take it off before you swim until Google says otherwise.

Whoop's Strap 5.0 runs about two weeks between charges, which is double the Air, so battery life is not where this band wins. Price is.

Specification

Which of these four you actually want

CoolCuration now has pages on four of these, and they are not interchangeable. The short version:

• Buy the Fitbit Air if you want recovery and sleep data, want to stop looking at a screen on your wrist, and do not want to spend three figures.
• Buy the Oura Ring 4 at £349 if you want the same screenless idea on a finger rather than a wrist, and you are willing to pay four times as much for it.
• Buy the Pixel Watch 4 from £279 if you run Android and want notifications, payments and built-in GPS as well as the health tracking.
• Buy the Fitbit Versa 4 at £179.99 if you want a screen and onboard GPS but not a full smartwatch.

The Air is the only one of the four with nothing to look at, and it is the cheapest by £95.

Frequently asked questions

How much does the Fitbit Air cost in the UK?

£84.99, checked on Amazon UK on 6 September 2026.

Does the Fitbit Air need a subscription?

No. Heart rate, HRV, SpO2, steps and sleep all work without one. Google Health Premium is £7.99 a month and adds AI coaching, and three months are included with the band.

Does it have GPS?

No, and no NFC either. Distance comes from your phone.

How long does the battery last?

Google says up to seven days and Tech Advisor got a full week out of one. The charger is proprietary, so older Fitbit cables will not fit.

Can it detect atrial fibrillation?

Google says it watches for the irregular rhythm associated with AFib and can flag it. That is a prompt to see a doctor, not a diagnosis, and the Air is not a medical device.

Does it work with an iPhone?

Yes, on iOS 16.4 and later, and on Android 11 and later.
