Rather than demand a three-figure annual fee like Whoop or target data-obsessed fitness fanatics like the Garmin Cirqa<\/a>, this everyman wearable has price on its side at just $100\/\u00a385. There\u2019s been no skimping on sensors, it has a battery that can go the distance, and the companion app won\u2019t bamboozle newbie exercisers with stats and charts. Comfort hasn\u2019t been forgotten either.<\/p>\n OK, Google will happily also charge you $10\/\u00a38 a month for AI-powered fitness and nutrition insights \u2013 but they\u2019re entirely optional (and, as I\u2019ll explain below, not for everyone). So as long as one or two absent features aren\u2019t enough to send you searching for a regular smartwatch or GPS watch, it\u2019s hard to see how casual exercisers can do any better.<\/p>\n How does the Fitbit Air\u2019s design differ from rivals?<\/p>\n Side-by-side with a Whoop, Cirqa or virtually any other screen-free fitness tracker you could name, the Fitbit Air is impressively small. At a hair over 8mm thick it takes up very little room on your wrist. The tracker also weighs next to nothing. Combined with a flexible fabric knit band that\u2019s infinitely adjustable, via velcro that grips tightly no matter what form of exercise is your favourite, and there were times during testing where I genuinely forgot I was wearing it. This is easily the comfiest in the class right now.<\/p>\n Not being overloaded with features surely helps. With no buttons to make room for and a status LED that can largely be ignored (it\u2019ll only flash to indicate charging status or firmware updates), this is a set-it-and-forget-it wearable. Only the vibration motor will remind you of its presence on your wrist, and even then only for irregular heart rhythm alerts, low battery warnings and a silent alarm. You can\u2019t set it to buzz for incoming texts or calls. <\/p>\n The stretchy fabric wrist band would be my pick for daily wear; it\u2019s fantastic for sleep and comes in a bunch of jazzy colours beyond the rather reserved black of my review unit. Swimmers may want to swap it out for the quick-drying silicone version, though. The tracker pops out with a bit of force and clips back in just as easily, so there are no tricky clasps or release mechanisms to struggle with.<\/p>\n Google doesn\u2019t have any official bicep straps or accessories to wear the Air anywhere other than on your wrist, like Whoop does, but a quick search online suggests there\u2019s already a burgeoning third-party market.<\/p>\n How good is the Fitbit Air at health & fitness tracking?<\/p>\n It may be small, but Google found enough room inside the Fitbit Air for heart rate, SpO2 and skin temperature monitoring as well as an accelerometer\/gyroscope. That\u2019s enough for it to record your resting heart rate, blood oxygen saturation and heart rate variability, on top of simpler metrics like step count.<\/p>\n Google Health takes all these and calculates more at-a-glance figures, like a daily readiness score and a weekly cardio load. These are great for deciding whether today is the day to tackle a personal best, or to take it easy and give your body time to recover. The results were largely in line with Garmin\u2019s body battery metric, based on data recorded by the much more expensive Fenix 8 Pro<\/a> smartwatch.<\/p>\n Sleep scores were also consistent with more expensive wearables, with sleep and wake-up times within a few minutes of my Garmin. Sleep stages weren\u2019t an exact match, but neither is exactly medical-grade, so it gets a pass. There\u2019s plenty of detail within the app if you want to monitor restlessness or sleeping heart rate.<\/p>\n Workouts will take some adjustment if you\u2019ve previously used a smartwatch or tracker with a screen. Now you\u2019ll either be ignoring data altogether until you\u2019ve finished an exercise, having it announce exercise stats audibly through your phone based on time or distance, or looking to your phone\u2019s screen for real-time data within the companion app.<\/p>\n If you don\u2019t start an activity this way, the Air will begin recording automatically after 10-15 minutes depending on the exercise. You can tweak this in the settings if, for example, you don\u2019t want it counting your 20 minute walk to work as exercise. It recognises walks, runs, cycles and rowing machines, but there are over 100 more to tag a workout as through the app.<\/p>\n The Air also monitors all your metrics 24\/7, so if something gets missed (which in my experience rarely happened) you can retroactively add it via the app; that\u2019s not an option on the Garmin Cirqa, which costs twice the price. Tracking accuracy is generally excellent for a wrist-based wearable. Step, heart rate and distance results all aligned with a more expensive smartwatch. <\/p>\n There\u2019s no ANT+ on board like the Cirqa, but you can share live heart rate data with other devices over Bluetooth which is a well-deserved silver medal. Many more expensive smartwatches can\u2019t do that without a third-party app.<\/p>\n The only real negative is a lack of onboard GPS, meaning you\u2019ll have to bring your phone along during activities to record location data or track with even better distance accuracy. This is also the case for most rivals, though, so if not having maps from a single device is a dealbreaker then a screen-free tracker may not be for you.<\/p>\n What makes the Fitbit Air\u2019s companion app stand out?<\/p>\n Like any screen-free fitness tracker, the FitBit Air is nothing without a companion app. Happily, Google\u2019s is the most user-friendly I\u2019ve come across to date. Google Health has fully replaced the old Fitbit app with an uncluttered and customisable interface that lets you put the numbers that matter most front-and-centre.<\/p>\n The app is available for both iOS and Android, so iPhone owners aren\u2019t missing out, and it plays nicely with Google\u2019s Pixel Watch range. It\u2019s smart enough to merge data when wearing a Watch for workouts but the Air the rest of the time, rather than duplicating it, and has no problem spitting out your data to third-party apps or services such as Strava. <\/p>\n If you just want the basics, that\u2019s all there is to it: fitness, health and sleep are split into different pages, each with layers of data to dig through. I found everything easy to digest and not nearly as overwhelming as something like Garmin Connect. <\/p>\n Pay \u00a380 a year for a Premium subscription, however, and Google\u2019s AI-powered Health Coach can translate all those numbers into short paragraphs of text analysing your most recent sleep, last workout, and daily activity roundup. It can also estimate calories for your nutrition goals based on photos of your food and create tailored workout plans, customisable through a chatbot interface. <\/p>\n I told it the hours I typically had free on weekdays and weekends around work and childcare, what workouts I enjoyed, and my overall fitness goals. It then spat out a plan covering multiple lunchtime runs and two longer sessions on my Zwift Ride<\/a> static bike. When I noted I had a work trip coming up, it changed the plan to include early morning gym sessions instead. I liked how I could take a photo of a treadmill run and add it to my workout diary, without having to tap anything in manually or download a third-party app first. <\/p>\n There\u2019s an ease of use here that goes way beyond what rival wearables are offering with their AI features. Whether they are worth paying for depends on if you\u2019d rather plan your workouts yourself, or find conversing with a disembodied text prompt at all motivating. You do get three months bundled in for free with purchase to try it out, and Google includes Health Premium with its more general subscription offerings like AI Pro; if you\u2019re already paying for extra Google Drive storage, you might find you already qualify for this. <\/p>\n While I\u2019ve yet to test them, Google will soon be adding blood pressure trends, insulin resistance trends and sleep breathing quality metrics as part of the premium package \u2013 though these rely on algorithms rather than actual readings, so I\u2019ve no idea whether they\u2019ll be worth paying for.<\/p>\n How good is the Fitbit Air\u2019s battery life?<\/p>\n Officially, the Fitbit Air will last for around seven days of 24\/7 wear. That\u2019s half what a Whoop 5.0 can manage and slightly less than the Garmin Cirqa \u2013 although things are a bit closer once the Garmin enables constant pulse ox monitoring. <\/p>\n In my testing, however, the Air has been something of an overachiever. On weeks with a handful of tracked exercises, rather than daily workouts, I got closer to ten days before needing to charge. Even with daily runs or gym sessions, I\u2019d be confident of travelling without taking the compact magnetic puck along with me.<\/p>\n There\u2019s no way to top up the Air while wearing it, unlike the Whoop, and a full charge takes about an hour and a half. I\u2019ve found a quicker stay while I shower and get dressed in the morning is plenty for getting through at least the next twenty four hours, though. You\u2019re lasting comfortably longer here than any mainstream smartwatch: a Samsung Galaxy Watch Ultra2 or Apple Watch Ultra 4 will struggle to get to a third day before begging for a trip to the plug socket.<\/p>\n Should you buy a Fitbit Air in 2026?<\/p>\n Do you want a distraction-free fitness band that tracks multiple health metrics \u2013 and tracks them well? One that doesn\u2019t cost the earth, either up front or annually through a subscription? Look no further than the wonderfully slim, comfortable and long-lasting Fitbit Air.<\/p>\n Google has delivered an impressively well-rounded device, which doesn\u2019t gate off its headline features if you decide AI insights aren\u2019t worth paying extra for. The companion app is the most user-friendly I\u2019ve tried, clearly detailing every exercise and health stat the average fitness fan could want \u2013 whether you\u2019re subscribed or not. <\/p>\n Only Garmin die-hards that refuse to leave Connect should consider a Cirqa instead, while serious amateur athletes or above should still budget for Whoop\u2019s expensive annual membership for its more in-depth strain and training load analysis. <\/p>\n What are the Fitbit Air\u2019s technical specifications?<\/p>\n ScreenNoneSensorsHeart rate, accelerometer, SpO2, temperatureConnectivityBluetoothDurability5ATMBattery lifeUp to 7 daysDimensions35x17x8.3mm, 5.2g (tracker only)<\/p>\n \t\t\t![\"Google](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/09\/Google-Fitbit-Air-review-on-wrist.jpg\")
