Fitbit Air First Impressions: Google’s New Fitness Tracker Has a Built-In Coach


Google is ditching the screen on its latest wearable and betting hard on its AI health coach. The new Fitbit Air is a slim, screenless band with a removable sensor with the sole job of collecting health data in the background, removing the distractions of notifications, apps and stats.

This back-to-basics move echoes the earliest Fitbit devices, but with a very different end game. Where those first bands only counted steps, the Fitbit Air feeds a much broader stream of biometric data into Google’s evolving health ecosystem that seems to be increasingly centered on AI.

At $99, the band is just the ticket to get you in the door. The main event is Google’s recently launched Health Coach, part of the Google Health Premium (formerly Fitbit Premium) service. The premium service will run $10 a month or $100 a year when you purchase an annual subscription. 

Health Coach is an AI-powered chatbot built on Gemini that translates raw data into personalized guidance, adaptive workout plans and recovery recommendations.

The strategy also extends beyond Android. Because the Fitbit Air and its companion app support both iOS and Android, Google is using the device as a Trojan horse of sorts to bring its AI health coach to iPhone.

News of the launch comes alongside a broader rebrand, as Google phases out the Fitbit name in its app in favor of Google Health — part of a push to unify its wearables, services and AI. The Fitbit branding sticks around on hardware for now, but the finish line for the Fitbit name is in sight.

It’s also a strategic bet on where the market is headed. Screenless devices like the Whoop band and Oura Ring have carved out a growing category of wearables focused on continuous wear, sleep tracking and long-term health trends rather than the in-the-moment functionality of a smartwatch. The fact that the Fitbit Air can be paired with a device like the Pixel Watch further suggests Google sees the two as complementary, not competitive.

What does it track?

The Fitbit Air covers the core health metrics you’d expect, including 24/7 heart rate monitoring, heart rate variability, SpO2 (blood oxygen level), temperature variation, sleep tracking and analysis, cardio load, training readiness, steps, distance and irregular heart rhythm notifications for atrial fibrillation detection. It also includes automatic activity tracking that you can confirm later in the app. The device is water-resistant up to 50 meters.

One caveat: The Fitbit Air uses an older sensor setup than the current Pixel Watch 4, which includes a multipath optical heart rate sensor and a far-field temperature sensor. The Air sticks with more traditional sensors, which could limit accuracy, especially in peak heart rate zones and for more advanced insights, like menstrual cycle tracking.

Google’s coaching superpowers 

Google Health Coach, and the long-term health insights, are the main reason you’d buy this band. The coach pulls together fitness, sleep, heart rate and menstrual cycle data to build training plans that adapt to real-time performance and schedule. It sets weekly targets and can suggest workouts (which include video examples), adjust recommendations based on recovery and can use your own data to signal when to push and when to rest. This includes haptic Smart Wake alarms that use your sleep data dynamically to wake you at an optimal point in your sleep cycle.

Health Coach has been in beta since October of 2025 and is rolling out in a staggered launch alongside the Fitbit Air.

Battery life

One of the clearest advantages of going screenless is battery life. Google says the Fitbit Air lasts up to a week on a single charge. (We’ll have to test to see how this holds up to our real-world testing.) And it can also charge from zero to 100% in 90 minutes. 

That doesn’t quite match the Whoop band’s two-week battery life, but it’s a serious step up from the roughly 36-hour battery cap you’d get from its display-totting siblings, like the 41mm model of the Pixel Watch 4.

iOS and Android

Unlike the Android-only Pixel Watch, the Fitbit Air works with both Android and iOS, which is more in line with other Fitbit devices. That means you can get the Google Health Coach even if you have an iPhone, though it’s unclear if there are any advantages to using the Air on Android versus iOS. 

Design and fit 

I haven’t seen the Fitbit Air in person yet, but based on the specs, it follows a familiar screenless design. Like the Whoop band, the sensor module can be removed and swapped between different bands. Unlike Whoop, which offers alternate mounts such as a sports bra and even a Whoop thong, Fitbit is sticking to wrist-based accessories. That may change later based on feedback. 

The Air supports a range of interchangeable bands in different materials. Options include the Performance Loop for everyday wear, the Active Band for workouts and the Elevated Modern Band for a more polished look. Bands start at $35 and come in four colors: Obsidian, Fog, Berry and Lavender. An orange and gray Stephen Curry Special Edition will also be available in limited quantities.

The privacy dilemma

The shift toward Google Health branding is now prompting renewed scrutiny, particularly as the company explores letting users import medical records to the app. As part of its 2020 acquisition of Fitbit, Google agreed to keep Fitbit health data separate from its advertising business for 10 years. 

Google says data collected by the Fitbit Air and other Fitbit devices will not be used for advertising, but experts have noted that even anonymized health data can often be traced back to individuals, and that once data is collected, how it’s used years down the line depends entirely on policies that can change. For anyone considering handing over their health data, it’s worth reading the fine print and keeping an eye on how those policies evolve over time.

The Fitbit Air detects workouts automatically and stores them in the Google Health App.

Fitbit Air pricing and availability

The Fitbit Air launches May 7 for $100 at Google.com and in the Google Store app, with in-store availability at physical retail locations beginning May 26. Accessory bands start at $35.

Three months of Google Health Premium are included with purchase, after which the subscription automatically renews at $10 a month. 

CNET will be testing the Google Fitbit Air over the coming weeks, so check back for our full review.

Iceland doesn’t ease you in.

We landed at Keflavik Airport just as the sun was going down — and the views from the plane on descent were already something else. Golden light spilling across a volcanic landscape that looked like nothing I’d ever seen from 30,000 feet. That was our welcome to Iceland.

Four days later I left having seen the Northern Lights twice, walked inside a glacier, stood on a black sand beach in 50mph winds, and found a place that looked so much like Mars I genuinely had to remind myself I was still on Earth.

This is the exact route we took — every stop, every restaurant, every moment worth knowing about. My dad and I did this trip in January with Secret Spots Iceland, a local tour operator who knows these locations better than anyone. If you want a guided experience, they’re worth every penny. That said, every stop in this Iceland winter itinerary is completely doable on your own — and I’ll give you everything you need to navigate it independently.

Before you pack — check out our Iceland Packing List for exactly what to wear and bring. Waterproof everything. Trust me.

Before You Go: The Winter Light Reality

One thing nobody fully prepares you for in Iceland in winter the sunlight window is tiny.

Sunrise wasn’t until around 10:30am and sunset hit at roughly 4pm. That’s less than six hours of daylight. It sounds limiting but it actually works in your favor, the golden hour light lasts all day, every photo looks incredible, and the darkness gives you the best possible conditions for Northern Lights hunting.

Plan your driving between stops accordingly. Don’t underestimate how quickly it gets dark.

Day 1: Reykjavik & The Northern Lights

Keflavik Airport → Reykjavik (45 minutes)

Reykjavik

Flying into KEF is a dream. Grab your 4×4 rental car immediately, this is non-negotiable in winter, don’t even consider a standard vehicle — and make the 45-minute drive into Reykjavik.

Spend your first afternoon and evening exploring the city. It’s compact, walkable, and packed with personality. The main landmark is Hallgrímskirkja, the iconic church that towers over the city and gives you sweeping views over the rooftops from the top. Walk Laugavegur Street for coffee, food, and a feel for the city.

Eat somewhere local. Reykjavik punches well above its weight for food.

Reykjavík → Hvolsvöllur (90 minutes)

Hvolsvöllur

Here’s the decision that changed our entire trip: instead of staying in Reykjavik, we drove 90 minutes east to Hvolsvöllur for the night.

The reason? Light pollution. Reykjavik’s glow kills your Northern Lights chances. Hvolsvöllur is deep in the South Iceland countryside, dark skies, privacy, and dramatically better odds of catching the aurora.

It paid off immediately.

Within minutes of checking into our Airbnb, I glanced outside and noticed the sky looking a little more colorful than usual. I walked out. The Northern Lights were directly above us, green ribbons moving across the entire sky, on night one within an hour of arriving.

We spent 45 minutes outside. Just standing there, staring, filming, not saying much. One of those moments where you understand immediately that you’ll remember it for the rest of your life.

If you’re chasing the Northern Lights, and want to get the most out of this Iceland winter itinerary, get out of Reykjavik at night.

Day 2: The South Coast – Waterfalls, Black Sand & Basalt

The South Coast is Iceland’s greatest hits. Give yourself a full day and don’t rush any of it.

Seljalandsfoss

Seljalandsfoss

Your first waterfall, and what a way to start.

Seljalandsfoss drops 60 meters off a cliff face and, uniquely, you can walk behind it through a narrow passage carved into the rock. Standing behind a waterfall while it crashes in front of you is a genuinely surreal experience. The mountains flanking it on both sides make the backdrop even more dramatic.

Wear your waterproof gear here. You will get wet. That’s not a warning, it’s a promise.

Reynisfjara Black Sand Beach – Near Vík (R.I.P.)

Reynisfjara Black Sand Beach

We were lucky enough to be some of the last visitors to experience Reynisfjara before a section of the cliff collapsed, permanently changing the beach.

Even before that, this place was unlike anything I’d ever seen. Black volcanic sand as far as you can see, enormous basalt columns stacked like organ pipes along the cliff face, and waves arriving with absolutely zero warning.

The wind here was brutal. My dad had forgotten his waterproof pants and within minutes he was completely soaked. I was fine. Wear your waterproof gear. All of it.

The rogue waves at Reynisfjara are genuinely dangerous, people have been swept away here. Stay well back from the waterline no matter how calm it looks.

Lunch at Ströndin Pub – Vík

After Reynisfjara, stop in Vík for lunch at Ströndin Pub. I had one of the best burgers I’ve eaten anywhere. Warm, unpretentious, and exactly what you need after getting sandblasted on a black sand beach.

Skógafoss

End the day at Skógafoss and save energy for it because this waterfall deserves your full attention.

Unlike Seljalandsfoss where you walk behind the water, at Skógafoss you walk directly underneath it. The scale is enormous, 60 meters of water crashing down so close you feel the full force of the mist on your face. Don’t be scared to get close. The photos are worth it.

Climb the stairs to the viewing platform at the top for a completely different perspective over the South Coast.

Day 3: Ice Caves, Glaciers & The Best Pizza in Vík

Yoda Cave

Yoda Cave

Start the morning at Yoda Cave, a lava tube formation whose jagged entrance looks almost exactly like the Star Wars character. I didn’t realize it until we got there and then couldn’t unsee it.

The best part? We were completely alone. No other visitors, no tour groups, just us walking into a cave on a black sand beach feeling like genuine explorers. Coming out alive was a bonus. (Just kidding. Mostly.)

The adjacent black sand beach gives the whole spot an otherworldly backdrop that made it one of the most photogenic stops of the entire trip.

Glacier & Ice Cave Tour with KatlaTrack – The Experience of a Lifetime

Katlatrack Glacier & Ice Cave

Clear your afternoon. This tour runs about 3 hours and it is without question, one of the most unforgettable experiences of my life.

The guide loads you into what can only be described as a war-ready 4×4 and takes you off-road across a glacier. It feels like driving on another planet. When we reached the ice caves, the scene was straight out of Interstellar, icy mountains on every side, electric blue walls of compressed glacial ice, complete silence except for the crunch of boots on ancient ice.

We spent the next hour or two trekking in and out of the caves. Every turn revealed something more extraordinary than the last.

Wear every layer you brought. It’s cold, it’s wet, and it’s worth every second of discomfort.

Book KatlaTrack in advance, this tour sells out. Don’t leave it to chance.

Dinner at Black Crust Pizzeria – Vík

Back in Vík for dinner. There’s really only one pizza place in town Black Crust Pizzeria, and honestly, that’s fine. It’s excellent. After a day on a glacier, it’s exactly what you need.

Day 4: The Golden Circle – Craters, Geysers & Iceland’s Bluest Waterfall

The Golden Circle is Iceland’s most famous tourist route for a good reason. But we did it with a few detours that most visitors never find, and those ended up being the best moments of the day.

One important note for winter: sunrise on this day was around 10:30am. We timed our first stop perfectly for the golden hour light. Plan your Golden Circle day around the sunrise.

Ingólfsfjall – Sunrise Overlook

Ingólfsfjall

On the way to Kerið, we spotted a beautiful overlook called Ingólfsfjall and pulled over on instinct. The timing was perfect, it was right at sunrise, the light was golden, and the views over the surrounding landscape were extraordinary.

This is the kind of stop that doesn’t make it into most itineraries. Pull over for it. The drone shots here were some of my favorites from the entire trip.

Kerið Crater

Kerið Crater

A volcanic crater lake that looks like it fell from another dimension. Deep red and black crater walls surround vivid teal water at the bottom, the color contrast is almost artificial looking, especially in winter light.

Walk the entire rim and go down to the water. The perspective changes completely from every angle you view it from. Don’t just look from the top and leave.

The Secret Spot (Near Kerið – You’ll Know It When You See It)

The Secret Spot

Just a short distance from Kerið, we found a place I’m deliberately not naming or mapping.

The entire landscape was varying shades of red, orange, and black. So alien-looking that the only reference point I had was Mars. We had the whole place completely to ourselves. No other visitors. Just us, the drone, and a landscape that genuinely didn’t look like Earth.

We flew the drone all around and spent time just sitting with it, reflecting on how one country can contain ice caves that feel like Interstellar AND a red volcanic landscape that feels like Mars. Keep your eyes open on the roads around Kerið. You’ll recognize it immediately when you see it.

Gullfoss

Gullfoss

One of Iceland’s most iconic waterfalls, and one of the rare ones that actually lives up to every photo you’ve ever seen of it.

Gullfoss is so wide and encompassing that it made me feel genuinely small, which nature has a funny way of doing when it wants to put you in your place. Visit every viewpoint, each one gives you a completely different experience of the same waterfall. My favorite was the lower platform where you can feel the full force of it, mist was blowing directly into my face the entire time and I couldn’t have cared less.

Geysir – Strokkur

My first geyser. It didn’t disappoint.

Strokkur erupts every 7-10 minutes, shooting boiling water 20-30 meters into the air. The challenge is being ready with your camera every single time. Your arms will get tired holding the shot but the moment it erupts is absolutely worth it. You’ll watch it four or five times before you’re ready to leave.

There’s a visitor center right next to the geysir with a food court and a gift shop if you need to grab something for whoever you left at home.

Brú Horse Farm

Brú Horse Farm

A quick stop that became one of the warmest moments of the trip. Iceland’s native horses are a breed unlike any other, small, thick-maned, and completely uninterested in you unless you have snacks.

Buy the snacks. It’s the only way to get a good photo and honestly the horses’ complete mercenary attitude toward humans is hilarious and endearing at the same time.

Brúarfoss Waterfall My Favorite of the Entire Trip

Iceland’s bluest waterfall and the most undervisited stop on this entire itinerary.

The water here is a vivid cobalt blue that doesn’t look real. It’s fed by glacial meltwater filtering through ancient lava rock, and the color it produces is unlike anything else in Iceland. With the mountains in the background it was the most purely picturesque waterfall of the whole trip, not the biggest, not the most powerful, but the most beautiful.

Most Golden Circle visitors skip this entirely. Don’t be one of them.

The waterfall is intimate and quiet in a way that Gullfoss and Skógafoss aren’t. I flew my drone up and over it for some of the best footage of the trip. And then I just sat there for a while. Some places make you want to stop moving and just exist in them for a minute. Brúarfoss is one of those places.

Þingvellir National Park – End on a High

The final stop, and the right one to end on.

Þingvellir is where the North American and Eurasian tectonic plates meet above ground, creating a dramatic rift valley you can walk directly through. It’s also where Iceland’s first parliament was established in 930 AD, making it the most historically significant place on the entire route.

If you’re a Game of Thrones fan, there’s a section that will immediately remind you of the entrance to the Eyrie. You’ll recognize it the moment you see it.

We arrived at sunset. Overlooking the massive lake in that light, with the rift valley stretching out in every direction, it was the perfect way to close out four days in Iceland.

One Last Gift – Northern Lights at the Airport

Northern Lights

We ended the night at Keflavik Airport waiting for our flight home. And Iceland gave us one final send-off, the Northern Lights appeared directly above the airport while we waited to board.

Twice in four days. Iceland doesn’t do things halfway.

FAQ

Should I rent a car for my trip to Iceland in winter?

4×4 is mandatory in winter. Non-negotiable.

How long is it day in Iceland?

Sunrise ~10:30am, sunset ~4pm in January (Roughly 5 hours of daylight). Plan accordingly.

Should I hire a guide or go on my own?

We used Secret Spots Iceland for Days 2 and 3, which gave us access to spots and knowledge we wouldn’t have found on our own. Every stop in this itinerary is doable independently — but if you want a local expert showing you the less-obvious spots, they’re excellent.

What are the road conditions in Iceland in winter?

Check roads on a daily basis. Iceland’s conditions change fast and F-roads close in winter without warning.

Where can I see the Northen Lights?

Get out of Reykjavik at night. The further from city lights the better. Download the Aurora app for real-time forecasts.
