Google Store UK sells the Fitbit Inspire 3 for £84.99, or £28.33 a month over three instalments, in Midnight Zen, Lilac Bliss and Morning Glow. The listing leans on two numbers, a battery claim of up to 10 days and a water rating of 5 ATM, and on a software split that decides whether £84.99 is the whole cost or the first payment.
The figures below come from Google's UK store pages for the tracker and for Google Health Premium, its returns page and its UK warranty text. Google's footnotes say the heart rate, blood oxygen, sleep and stress features are not intended to diagnose or treat any medical condition, and nothing here is medical advice.
Our verdict
Buy it at £84.99 for steps, heart rate and sleep tracking, with your phone supplying GPS. Treat Premium coaching, £7.99 a month after the trial, as a separate purchase; SpO2 and HRV are not confirmed for UK accounts.
- A good fit for
- People who want a small screen-forward tracker with a ten-day battery claim and are fine running a Google Account and the Google Health app on Android 11+ or iOS 16.4+.
- We would skip it if
- You want onboard GPS, refuse a Google Account, or are buying mainly for coaching or for SpO2 and HRV readings, which Google's UK pages do not confirm.
Reasons to consider it
- Up to 10 day battery claim, a two-hour charge, and both band sizes in the box, at £84.99 on the Google Store.
- Optical heart rate, SpO2 sensors, a device temperature sensor and an ambient light sensor on the spec sheet, with Connected GPS for pace and distance.
- A two-year manufacturer's warranty for UK purchases, on top of statutory rights.
The compromises
- No onboard GPS; pace and distance use Connected GPS from your phone, so the phone has to come along.
- Google's SpO2, skin temperature, HRV and breathing rate notes say not available in all markets or only in select countries, and none of them names the UK.
- The wellness report PDF, detailed stress breakdown, most mindfulness sessions, workouts and the Gemini coach need Google Health Premium at £7.99 a month after the trial.
What we have not verified: The Google Store UK pages mark SpO2 and skin temperature not available in all markets, and HRV and breathing rate available only in select countries, without naming the UK, so whether those four readings appear for a UK account is the open question that could change the verdict. Irregular rhythm notifications are likewise limited to select locations on Google's help page, with no country list. Battery, heart-rate, sleep and stress figures are Google's claims, and Google says charge cycles vary with use. Google Store is the only UK seller read, so £84.99 is Google's own price and not a market range.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Fitbit Inspire 3
Both band sizes come in the box, the sensor list covers heart rate, SpO2 hardware and skin temperature at this price, and the Google Health app's free column lists activity, sleep and heart-rate tracking without a membership.
Before you buy: Coaching, workouts, the wellness report and most mindfulness sessions need Google Health Premium, £7.99 a month after the trial, and the UK store pages do not confirm SpO2 or HRV for the UK.
Price checked 17 October 2026. Retailer prices can change.What £84.99 buys on paper
The spec sheet lists a 3-axis accelerometer, an optical heart rate monitor, red and infrared sensors for SpO2, an ambient light sensor, a device temperature sensor and a vibration motor. The display is AMOLED under Corning Gorilla Glass 3, the only radio is Bluetooth, and the body weighs 17.69 g at 39.32 mm long by 18.6 mm wide. Memory holds seven days of minute-by-minute motion data and thirty days of daily totals, with heart rate stored every second during tracked exercise and every five seconds otherwise.
The box holds the tracker, a charging cable and the Classic wristband in both sizes. Google gives the small band a 130 to 190 mm wrist range and the large band 160 to 220 mm, so there is no wrong-size gamble. The band is silicone with a plastic buckle and tang. Google also promises at least two years of security updates after the device is last sold on the Google Store.
Battery and water claims, with Google's caveats
Google states battery life of up to 10 days and a zero-to-full charge in two hours on a lithium-polymer cell. The specs page adds that battery life and charge cycles vary with use and settings, and recommends charging every few days. Two listed features carry a battery cost: SpO2 tracking says it requires more frequent charging, and always-on display mode says it may, so anyone who switches both on should expect something short of ten days.
The water rating is 5 ATM under ISO 22810:2010, which the specs page describes as water resistant to 50 metres. The fine print is direct: the tracker is not waterproof, resistance fades with wear, repair or damage, a drop can end it, and it is meant for shallow water, not water at high velocity or high temperature.
Health readings, and the country notes Google attaches
The overview lists 24/7 heart rate, resting heart rate, high and low heart rate notifications, SpO2 tracking, skin temperature variation, heart rate variability, breathing rate, sleep stages with a Sleep Score, a daily Stress Management Score and irregular heart rhythm notifications. Google's footnotes say the SpO2, HRV, breathing rate and stress features are not intended to diagnose or treat any medical condition, and the Inspire 3 is a wellness tracker, not a medical device.
The UK-specific question is availability. The store page marks SpO2 and skin temperature not available in all markets, and HRV and breathing rate available only in select countries; the specs page repeats the SpO2 and skin temperature notes. None of them names the UK. Google's help page lists the Inspire 3 for irregular rhythm notifications but says they are only available in select locations, again with no country list. A buyer purchasing for those readings is working from an unconfirmed list.
Returns, warranty and account requirements
The Google Store return page says most items can be returned within 15 calendar days after the day you receive them, and names no UK-specific term. Google's Hardware Warranty Centre sends Fitbit hardware bought on or after 11 July 2023 in the United Kingdom to a limited warranty that runs two years from original purchase. Google calls it a voluntary manufacturer's warranty that sits beside your statutory rights; it covers hardware only and excludes consumable parts such as batteries unless the failure comes from a defect in materials or workmanship.
Platform requirements are firmer than the warranty. The Fitbit app is now the Google Health app, setup needs a Google Account plus internet access, and the phone must run Android 11 or newer or iOS 16.4 or newer. Syncing uses Bluetooth LE with a stated range of up to 30 feet. An older phone or a refusal to use a Google Account rules out the device, not just Premium.
When to skip the Inspire 3
Skip it if you run or ride without your phone and want pace and distance recorded. The Inspire 3 has no GPS of its own and relies on Connected GPS, while the Charge 6 at £139.99 on the same store lists built-in GPS. Skip it if a Google Account is a dealbreaker, and if you expect ten days of battery with SpO2 and the always-on display both running.
Skip it as a coaching product unless you have priced the membership at £7.99 a month after the trial, and skip it if SpO2, HRV or irregular rhythm notifications are the reason to buy, since the UK pages do not confirm them. Buy it when a small, long-battery band with free tracking and phone-borrowed GPS is the whole plan.
