Google Fitbit Air: One minute review
For a simple device, there’s a lot going on with the Google Fitbit Air. People feel very strongly about it, for better or for worse, and there’s been a lot of chatter and interest surrounding its release. My experience actually wearing the device has generally been very positive, with tracking accuracy comparable to that offered by my Apple Watch Ultra 3, which is pretty much the gold standard for wrist-based health tracking. Metrics relying on the tracker’s onboard heart-rate monitoring are reliable, matching the Apple Watch closely during work, rest, and exercise during my week with the Fitbit Air.
Set-and-forget trackers are clearly having a moment. Oura has released the Oura Ring 5 just one year after the Ring 4, and Whoop’s success has given rise to a number of copycats from brands looking to recreate the experience of a distraction-free screenless ‘focus band’ for a less premium price.
Google is one such copycat, but the screenless, slender form factor suits the Fitbit brand — the original Fitbit was a digital pedometer — down to the ground. It speaks to the core of what Fitbit used to be, before it became just another company churning out mediocre smartwatches running a limited proprietary operating system. Your Fitbit was always meant to be a discreet little device, and devices don’t come more discreet than the Google Fitbit Air. Weighing just 12g and using a very slender 17mm-wide band, the Fitbit Air is a lovely and (crucially) comfortable device to wear and use. It’s much more comfortable to wear during sleep than any full smartwatch I’ve ever tried (and I have tried a lot), or even the Whoop.
However, it’s hard to separate the Fitbit Air from the Google Health app, with Google’s redesign of the Fitbit app causing particular ire amongst Fitbit users. The app is a bit of a mess, and not intuitive to use, with features dotted all over the place. It feels like it’s designed to primarily function as a home for the AI Health Coach chatbot, which is very intelligent and perhaps the best in-app AI assistant I’ve tried, but it’s not the best way to operate a health app. Whoop’s balance of AI and on-page metrics is much better.
If you’re looking for a consistent screenless focus band to track different sorts of workouts like gym, sports, and yoga, alongside sleep, heart health and general wellness, you can use the Google Fitbit Air as is, paying just the up-front price, and keep your tracking simple.
Whether or not you can get onboard with the Premium option will depend on how much you like chatbots — I found its flexibility immensely helpful, but its constant chirpy summaries and insistence on hiding my data inside walls of text became annoying, so it’s a mixed bag for me. Overall, though, this is the best, most interesting Fitbit to have been released in years.
Google Fitbit Air: Price and availability
- $99.99 in the US
- £84.99 in the UK
- AU$199 in Australia
The Google Fitbit Air costs $99.99 / £84.99 / AU$199, and for that you get the tracker, a band of your choice, and a charger specific to the Google Fitbit Air — proving once again that Google seems to be allergic to making a charger that’s compatible with more than one device.
The Google Health Premium subscription, which gives you access to Google’s AI Health Coach, costs $9.99 / £7.99 / AU$14.99 a month, or $99.99 / £79.99 / AU$140 annually. Existing Google AI Pro members get it at no extra cost.
For comparison, the cheapest Apple Watch SE 3 starts at $249 / £219 / AU$399, while Whoop’s complex pricing structure begins at £169 / $199 / AU$299 per year for the lowest tier. The Google Fitbit Air’s pricing is cheap for what you get, with the Health Coach as an optional add-on rather than a mandatory subscription.
Google Fitbit Air review: Design
- Simple, screenless and elegant
- Light and comfortable
- App design is chaotic
The Google Fitbit Air’s design can be split into two components: the physical device, which is excellent, and the new Google Health app, which is a bit of a misfire.
Let’s start with the positives. The Fitbit Air comprises the tracker itself, and a wraparound band in a choice of three styles — a silicone Active band, the woven Performance Loop, or the polyurethane (pleather) Elevated Modern band. Each comes with their own color options, and a plastic clasp. On the underside of the tracker are the optical heart rate sensor, skin temperature sensor, and an accelerometer and gyroscope for counting steps.
It weighs just 12g, even with the Performance Loop strap, so it’s light and easy to wear, which is crucial for sleep tracking. I wore it on my right wrist, with a watch on my left during the day, and I didn’t feel like an obnoxious techie: unless someone looks closely, it just looks like a wristband, with the lack of a screen helping here. The Performance Loop strap that came with my review unit is the best-looking of the three options in this respect, but none of them look bad.
The tracker also has a haptic vibrate function — if you set an alarm in the app, this can be disabled with a tap on the top of the device. And that’s pretty much all the interaction you have with the sensor and band as a whole; everything else, as with one of the best smart rings or other screenless tracking options, is done via the app.
The app is where Google’s design falls down. Split into four tabs — Today, Fitness, Sleep and Health — the Google Health app features a dashboard with key metrics at the top, and insights or libraries of content below it.
But with information scattered across a quartet of tabs, it’s hard to find certain granular metrics or content you’re looking for compared to the old Fitbit app. I searched for Mindfulness content for 10 minutes before finding the five-minute meditation I was after, for example, and I often ended up starting new chats with the AI coach rather than resuming a chat from my history. It’s just not intuitive to use.
What is right in your face, for Premium users, is the AI coach, which cloaks your metrics in paragraphs of cheery text, so it takes longer to get to your information. It’s clever, and we’ll get onto its functionality in a moment, but I wish it summarized and contextualized less, and just offered more ‘glanceability’.
Google Fitbit Air review: Features
- Set-and-forget tracker with a haptic alarm
- Good metrics
- AI Health Coach is a flexible macro-feature
The Fitbit Air records the usual metrics you’d expect with a modern fitness tracker, including step count, heart rate, floors climbed, sleep stages, and so forth. Fitbit’s Daily Readiness score shows you how prepared your body is for exercise, based on recent activity and sleep scores, while it also surfaces weekly cardio goals, hydration, and basic food logging. It can offer irregular heart rate rhythm notifications, which is great for potentially diagnosing atrial fibrilation, and allows you to take an ECG scan manually to monitor your heart health.
Basic tracking is all the free version gets you; there’s no workout builder, mindfulness content, way to log sickness, or any other extras beyond the numbers. It doesn’t add any special metrics for runners, such as stride or cadence, as many of the best running watches do. For some users who just want the numbers, this will be fine, with no need to subscribe to the Premium tier.
For Premium users, food logging can be done via the AI Health Coach, by taking a picture of your food. It’s very good at logging packaged food (it was bang on logging a crinkled package of chips with the message ‘log this’ as a 74kcal snack, also breaking down macros and salt content) but can struggle with plates of homemade food, although a basic description such as ‘log this lentil curry’ is enough for it to provide an estimation. The more information you can provide (weights and measures, etc), the more detailed it gets.
Those without the Health Coach can log food manually, as you can in other apps like MyFitnessPal.
The app also has access to Fitbit’s library of workout and meditation content, including individual moves, which you can use to build your own workout. Again, this is only available through the Premium subscription.
Through it all runs the AI Health Coach, which I actually found to be useful. Although there was no field to input illness as such, I typed my cold symptoms out to the Health Coach, and it remembered I was ill and adjusted its messaging and advice throughout the rest of the week based on my symptoms. I went to the gym without following one of the app’s pre-prescribed workouts, typed my sets and reps into the Coach’s ‘Ask Coach’ field, and it not only logged the workout, but suggested complementary routines to work different muscle groups for the rest of the week.
The AI Coach is a flexible ‘macro-feature’ that works well in conjunction with the rest of the app, and almost allows you to bypass the chaotic layout: you can just ask the Coach to serve you up what you need, which I’m sure was Google’s intent. Your use of the Coach will depend on your tolerance for chatbots: those who use Gemini or ChatGPT for everything will get a lot out of it, while those who loathe AI and just want numbers will likely loathe the Premium tier.
Google Fitbit Air review: Performance
- Performed well compared to the Apple Watch Ultra 3 in most scenarios
- Poor run estimations
- Battery life as described
As I noted when I compared the Google Fitbit Air against the Apple Watch Ultra 3, the tracker performed well during my 10K test run, at least for the metrics like heart rate and calorie count, which it can use its onboard sensors for. The metrics it uses my phone’s GPS to estimate, like distance, were off significantly.
I’ve embedded the results below, but generally there was no statistically significant difference between heart rate or calorie estimations from the two devices. I’ll be updating the review with confirmation of heart rate scores tested against a new Polar H10 chest strap, as my old testing unit has malfunctioned.
My experience of tracking my sleep with the same two devices — I wore one on each wrist — was similar to the above, with close enough metrics but slightly different outcomes.
The Fitbit Air’s total sleep time estimation was within five minutes of the Apple Watch, and sleep stages were similar. However, while my sleep score was 90 with the Apple Watch, Fitbit registered it as only 81, citing a 10-point difference in sleep quality. However, the Google Fitbit Air’s sleep tracking has consistently registered my wake-up times during testing, successfully recording my early-hours bathroom trips and my cat jumping on my legs at 5am.

Because of the lack of a screen, GPS, and specialist metrics, regular runners won’t get a whole lot out of the Fitbit Air. Compared to my usual wealth of data from Apple or the best Garmin watches, I found it lacking, and my GPS map — imported from my phone, as the Air has no GPS of its own —- inaccurate, off by 400m compared to the Apple Watch.
Battery life is excellent, exceeding the seven days the device promised. Charging is fast, with just five minutes delivering a full day of battery life, and a full charge taking around an hour. The device is very comfortable to wear, as previously mentioned — I’ve barely needed to take it off all week.
- Performance score: 4.5 / 5

How I tested
I wore the Google Fitbit Air for eight days straight. I ran a 10K while wearing an Apple Watch Ultra 3 and (malfunctioning) Polar H10 chest strap, and a shorter run with a Huawei Watch Fit 5 Pro, as comparison testing alongside my usual workout routines. I also wore the Apple and Fitbit side-by-side during sleep. I tested its alarm, tried the features of its premium Health Coach, and used the app’s workout and mindfulness content.
