My girlfriend got it for me as a gift, and honestly it has turned out to be one of the most useful tech gifts I’ve ever received.

Truly flawless for what it is and for the purpose it serves.

If you want to track the basics but also quite a few more advanced things around your health, sleep, and exercise, and generally “digitize” your daily life a bit, especially if you’re someone who likes technology and data, I think it’s one of the best choices.

It really measures a lot: steps, heart rate, resting heart rate, HRV, breathing, SpO₂, skin temperature changes, calories, cardio load, cardio fitness, and quite a few more.

For me, though, where it really stands out is sleep. It understands when you lay down, when you actually fell asleep, when you woke up, how much time you spent in Light / Deep / REM sleep, how many times you woke up or had restless sleep, and in the end it gives you a Sleep Score. So far I’ve found it frighteningly close to how I actually feel the next morning. On days when I slept badly and woke up tired, the score reflected that accordingly.

The vibration alarm function is also very nice. It wakes you from your wrist without sound, and you can increase the vibration intensity from the settings so that it actually wakes you up.

I also really like the Readiness Score, which essentially gives you an idea of how recovered and ready your body is, using data such as sleep, HRV, and your resting heart rate.

As for steps, I personally find it extremely accurate. I’ve seen reviews mentioning large discrepancies, but on my device I haven’t noticed anything like that. If someone is seeing completely absurd measurements, I’d suggest checking whether there’s an issue with the device or with how it’s being worn.

It also automatically understands when you’re exercising and then shows you what activity you did, the duration, and related data. This is one of the features I end up using more than I expected.

In terms of appearance, it’s exactly what I wanted: simple, discreet, and without a screen. I wear it all day and often completely forget it’s there. During the first 1-2 days the strap bothered me / scratched me a little, but then I got used to it and now I don’t notice it at all.

And I think the fact that it does NOT have a screen is one of its biggest advantages. I don’t want another smartwatch sending me notifications and demanding my attention. I want something that just sits on my wrist 24/7, records the data, and when I want to, I open my phone and look at it.

The battery is also excellent, with up to about a week of use, while the quick charge is very convenient.

Small tip: be careful with soaps, shampoos, etc. on the device itself. Google states that frequent exposure to such substances can gradually affect its water resistance. For cleaning, it’s better to follow Google’s official instructions.

The only thing I’m waiting for is for Google Health Coach / AI Coach to become fully available in our region as well. I believe that then the product will become even more interesting, because all that volume of data will be able to be turned into even more personal advice.

Finally, I see a lot of people comparing it to the Apple Watch, and in my opinion it doesn’t really make much sense. They are two different product categories. The Apple Watch is a smartwatch. The Fitbit Air is a screenless health/fitness tracker designed to be worn continuously and collect data without bothering you.

For the money I paid (~€130), I think the price/performance ratio is excellent. Especially for someone looking at Whoop-type solutions but who doesn’t want to spend €300+ on hardware and then depend on an expensive subscription, it’s an extremely interesting alternative.

5/5 from me. It was exactly what I was looking for.

the worst thing I have ever tried.
every night it writes 70cal/hour that I burn in my sleep.
you move your hand on the keyboard and it writes steps. i tried all the settings and it still writes wrong.
unacceptable quality in the strap.

it writes about 50% more steps than the phone, the band 7 and a samsung smart 4 that i had. completely unreliable

no difference in sleep, exercise, heart measurements from the band 7. that i had for so many years.

The Google Fitbit Air is very small, light, and discreet, to the point that you forget you’re wearing it. It tracks heart rate, sleep, HRV, SpO2, steps, and generally all the basic data you need.

The battery lasts about 7 days, which is a big advantage. A downside is that it has its **own charger**, so if you lose it or forget it, you can’t just use a USB-C cable.

Personally, I mainly use **Bevel**, because it presents sleep, recovery, and strain very nicely. And the important thing is that you can use it for free, so you don’t necessarily need to pay extra subscriptions every month.

On the downside, it also doesn’t have GPS and of course it doesn’t have a screen, so you can’t see data directly from your wrist.

Overall, if you want something like Whoop without a screen and without necessarily having a monthly subscription, it’s a very good choice.

I’m adding a screenshot from both Google Health and Bevel.

First impressions after a few weeks. I’ll come back later as well, of course, as its software evolves and Google continues tuning it.

If you want a tracker for the basics, lightweight, without a screen that can break during exercise, it’s ideal. I do climbing and this one has made things much easier for me, and I no longer have the fear that I’ll break a smartwatch against a wall or a rock. I imagine that for many other sports where the risk of damage is possible, it will be just as good. Also, personally, I can’t sleep with a watch on; it bothers me, so the Fitbit Air solved that problem for me as far as sleep tracking is concerned.

Obviously I don’t have an opinion on the AI because it’s not yet available in Greece, but from what I see on Reddit, most people aren’t satisfied yet either (and it’s also subscription-based). The fact that another user here in the reviews gave it one star just because it doesn’t have AI, I think, does it an injustice. Obviously the AI will come to Greece at some point too, but nobody knows when (so if you want it for the AI coach, don’t buy it yet).

Anyway, in my opinion and for my own needs, you don’t need the AI if you just want a decent tracker; it’s perfectly fine for standard workout tracking, and I haven’t seen it have major deviations or make significant mistakes so far. Its sleep tracking is good too — as good as sleep tracking can be when it’s done from a sensor on the wrist; that applies to ALL similar products.

That said, its software (the new Google Health app that replaced the Fitbit app) still needs quite a bit of work — in many things it’s worse than the Fitbit app, especially if you were used to it.

In conclusion, I consider it a good tracker for the basics (heart rate, sleep, cardio load, steps, workout tracking, etc.). Especially if watches bother you or you need something that won’t get destroyed during exercise and you want a decent tracker (with which you’ll see the results on your phone), then this is the solution.

Also, its battery is a BEAST. So far it lasts me more than a week. The band isn’t bad, but it’s not wow either. Google has released other better ones too, but they’re still not available in Greece and they’re expensive (of course they would be....). I do see that many people are happy with bands they found from other manufacturers (mostly from China, obviously).

Attention, Google AI coach is not supported in Greece. Without it, it is just a conventional tracker.
