This super-popular wearable is new, improved — and flawed

I received my Fitbit Air near launch day back in May, and I’ve had it on my wrist ever since. In our original hands-on coverage, I loved it for its lightweight design, long battery life, and 24/7 wearability, despite a lack of GPS tracking for runs, questions around data privacy, and an inconsistently reliable AI coach.

Three months later, I have more thoughts on how Fitbit Air has aged and whether or not I still recommend the device.

I find that it’s an inconsistent health partner.

Things I still love about the Fitbit Air? For starters, the size and weight have proven to be a huge selling point for the Fitbit Air. It’s so light and unobtrusive, I forget I have it on most of the time. Unlike larger fitness bands or even watches, its bracelet-like design makes it easy to wear in tandem with jewelry or accessories on the other wrist. Personally, I pair mine with an Apple Watch (I’m a data nerd; don’t judge), and I rarely dodge judgmental glances in public, so it must look normal to most folks.

Its covert aesthetic is further complemented by reliably impressive battery life that lasts slightly more than a week per charge, though this window may shorten a bit if you’re a real exercise fanatic. I rarely have to take it off or acknowledge it’s there, which is the best thing you could ask for in a dedicated fitness tracker. Considering that the Fitbit Air samples heart rate data every five seconds, this kind of battery life cannot be overstated. It’s truly impressive, as far as wearable gadgets go.

If there’s anything to gripe about, it’s that the pebble module inside the Fitbit Air is made of plastic. Sure, it’s lightweight and cheap to produce, but it’s also easy to damage. Shortly after the Fitbit Air launched, some users reported scratches on the heart rate sensor, and one unlucky user found out that bug sprays and plastics don’t mix. Keeping these in mind, I’ve been careful with my Fitbit Air, and it’s held up quite well so far, despite getting drenched for daily showers, occasional exercises, and rounds of dirty dishwater in the kitchen sink. Let’s see if that trend continues.

Things I dislike about the Fitbit Air

That’s not to say that Fitbit Air is perfect. When the device launched, Google heavily pushed its Gemini-powered AI health coach as a key feature. The company even rebuilt the Fitbit app around it as Google Health. Unfortunately, Coach still needs some work.

Through my day-to-day musings with Coach, I find that it’s an inconsistent health partner. Sometimes, it’s really good at making recommendations to improve personal fitness or serving as a soundboard for discussing random health questions. Other times?

It hallucinates over the data stored within the app. I’ve had it misread my readiness score, undercut my daily steps, and send me a morning notification to tell me I woke up too early while I was actively still sleeping.

One time, it even invented its own stress score, which is a feature Fitbit used to have, but it was removed when Google Health took over. When I asked Coach where it got the number, it said that I could find it myself in Google Health, but naturally, it wasn’t there. I’m still not sure where it found that hidden data, if it existed at all.

At this point, Coach is an interesting feature to play with, but it’s not actually reliable or useful yet. If it wasn’t already included in my Google AI Pro subscription, I wouldn’t dare spend the extra money on a Google Health Premium plan to try it out.

Would I recommend the Fitbit Air?

It’s only been a few months, but Fitbit Air remains to be one of the most interesting fitness trackers I’ve used in the last 15 years. Shortcomings aside, it does the basics well. Build, comfort, and battery are all highly rated in my book. It’s also tough to find a reliable tracker with class-leading heart rate, sleep, and fitness metrics for under $100. For the money, you get a lot of gadget here, and I would recommend it to anyone who is even the least bit curious about your health.

The story doesn’t end there, though. Fitbit Air is about to get better. Google announced at its hardware event in mid-August that the wearable is getting a powerful software upgrade. As part of Google’s new Health Guardian system for Pixel Watches, Fitbit Air will receive several quality-of-life features: insulin resistance metrics and blood pressure trends.

Together, these could theoretically help users detect early signs of diabetes and hypertension. That said, the features are expected to roll out in September, so I haven’t had a chance to test them yet. When they’re available, though, I’m sure I’ll have some thoughts. You’ll just have to wait until the six-month long-term review to read them.
