Fitbit Air UK Review: Google's £85 Screenless Tracker Tested

Google's Fitbit Air arrives in the UK — and the reviews are in

Google officially launched the Fitbit Air on 26 May 2026, following its announcement on 7 May. Priced at £84.99, the screenless, buttonless wrist tracker is now one of the most competitively priced dedicated health wearables available in the UK — and after several months in reviewers' hands, a clear picture is emerging of what it does well and where it falls short.

Wareable's full review, written by Michael Sawh and published on 16 September 2026, offers the most comprehensive verdict to date. The conclusion is broadly positive on hardware, more cautious on software: "The Fitbit Air successfully brings screenless fitness tracking down to a much more accessible price point, offering reliable core tracking, comfortable hardware, and a capable AI coach." However, Sawh adds that "a graph-heavy, cluttered Google Health app and paywalled advanced features keep it from greatness."

What the Fitbit Air actually is

The Air uses a two-part design. The main tracking unit — which Google calls "the pebble" — is a small pod made from polycarbonate and PBT plastics that slots into a swappable band. Google offers three core band types: Active, Elevated, and Performance. The whole assembly weighs 12 grams with the band attached, or just 5.2 grams without. Google says it is 25% smaller than the Fitbit Luxe and 50% smaller than the Inspire 3.

There is no display, no GPS, no NFC, and no buttons of any kind. What the Air does have is a strong sensor package: 24/7 heart rate monitoring, blood oxygen (SpO2) tracking, heart rate variability (HRV), sleep stage analysis with a Smart Wake vibration alarm, and continuous background AFib detection that is FDA certified. Battery life is rated at seven days, with a five-minute fast charge covering a full day's use. Water resistance is rated to 50 metres — notably deeper than Whoop's 10-metre rating.

The device also pairs with the Pixel Watch, meaning users can switch between wearables depending on the situation — wearing the larger device during the day and the Air at night or during workouts for additional comfort.

A barometer is absent, meaning altitude tracking requires carrying your phone simultaneously. Built-in GPS is also missing. Health Guardian features — covering blood pressure trends, insulin resistance trends, and sleep breathing quality — are listed as coming soon and will require a Google Health Premium subscription.

The software question

The Fitbit Air launched alongside the full rebrand of the Fitbit app to Google Health, which went live on 19 May 2026. The platform has been redesigned with Google's Gemini AI at its centre, powering what Google now calls the Google Health Coach — previously Fitbit Coach.

Google described the Air as a "discreet, screenless tracker" designed "with the Google Health Coach in mind," with sensor technology intended to give the coach the data it needs "to give you the most personalized guidance." Three months of Google Health Premium are included with the device, unlocking the AI coach, adaptive fitness plans, and detailed sleep insights.

After that trial, the subscription renews at $9.99 a month or $99 a year in the US — a $20 annual increase over the former Fitbit Premium price of $79.99. UK-specific post-trial pricing has not been confirmed. Google Health Premium is included at no extra cost for subscribers on Google AI Pro and Google AI Ultra; in the UK, the Google AI Pro tier costs £18.99 a month.

Wareable flags the "subscription-free" positioning as "not technically accurate," given that advanced features sit behind the paywall. The redesigned app itself has drawn mixed responses — reviewers note it has "lost some of the charm that made it so approachable and user-friendly" and now presents a graph-heavy, cramped interface that becomes busier still when the AI coach is active.

What UK reviewers said

Tech Advisor called the Air "an amazing achievement" that takes "the concept of Whoop's in-depth health analysis and opens it up to the masses with a budget price," describing the Gemini-powered Health Coach as "the real cherry on top."

Which?, testing the device in controlled lab conditions as of 28 August 2026, found "high-quality sensors that are impressively accurate" but awarded a "poor usability score for phone-free fitness tracking," citing "serious friction" in day-to-day use. The consumer group concluded that while £85 is "a fair baseline hardware price," the subscription model "severely complicate[s] its long-term value."

GadgetsAndWearables was more straightforwardly positive, noting that the overall value "works well, as long as you do not need a full smartwatch," praising the reasonable price, low-maintenance battery, and the fact that core data does not require a separate monthly subscription to access.

Known issues to be aware of

• The proprietary charger has been flagged as a practical irritation — losing it leaves no backup option.
• A sync delay means naps and some activity data can take hours to appear in the app.
• At least one reviewer noted noticeable phone battery drain from constant background sync.
• Stock issues at launch left some band variants — including the Active and Elevated Modern bands — unavailable for up to three weeks.
• Wareable notes the Air lacks the software polish and more comprehensive workout tracking found on the Whoop and, to a similar extent, Garmin's Cirqa.

The Fitbit Air is available now in the UK at £84.99. The device works with Android 11 or higher and Apple iOS 16.4 or higher, and requires a Google Account and an internet connection.
