Google Fitbit Air

About Google Fitbit Air

Overview Fitbit Air is the smallest tracker Google has shipped under the Fitbit name, and the cheapest way into its health platform. It has no screen. The device is a small pebble that clips into a band, records heart rate, sleep and blood-oxygen data continuously, and sends it to the Google Health app on a phone. At $99.99 it sits well below the subscription wearables it competes with, and the hardware is bought outright rather than rented. How Fitbit Air works There is nothing to read on the device itself. Google describes it as screenless by design, so the band stays silent on the wrist and the data lives in the app. The pebble pops out of its band, which means the strap can be swapped without replacing the tracker. Three band families are sold: the Performance Loop that comes in the box, an Active silicone band aimed at harder training, and an Elevated Modern band meant to read as a bracelet rather than a fitness device. Health and sleep tracking The sensor set covers 24/7 heart rate, heart rhythm monitoring with Afib alerts, SpO2, resting heart rate, heart rate variability, and sleep stages and duration. Sleep is the case Google makes most directly for the form factor: the device is light enough to keep on overnight, and Google suggests wearing a Pixel Watch during the day and switching to Fitbit Air for sleep. Google states the heart rate and sleep features are not intended for medical purposes, that the Afib feature is not intended for people under 22 with known atrial fibrillation or other known arrhythmias, and that it is not available in every country. Activity tracking Workouts can be started from the app, followed along with a guided session, or left to the device, which detects and tracks common activities on its own and sends a recap afterwards. Google says the automatic detection improves over time. Sessions can also be logged by hand, or photographed — pointing the camera at a piece of cardio equipment or a whiteboard circuit — though that photo logging requires a Google Health Premium subscription. Battery and charging Google quotes up to a week of battery life, measured in 2025 on pre-production hardware with a median usage profile, so real figures will move with the features you leave switched on. Fast charging is the more useful number day to day: five minutes on the charger returns a full day of power. Google Health and Premium The device is one half of the product; the Google Health app is the other. A three-month trial of Google Health Premium is included, and after that it renews at $9.99 per month unless cancelled. Premium is what unlocks Google Health Coach, the guidance layer that most of the marketing describes, and it is also bundled at no extra cost for Google AI Pro and Ultra subscribers. The device keeps working without Premium; the coaching does not. Special editions Alongside the standard model Google sells a Special Edition at $129.99, including one co-designed with Stephen Curry with a water-resistant coating and a raised interior print intended to improve airflow, and a Pokémon Sleep edition that pairs sleep tracking with the Pokémon Sleep app. These are the same tracker in different bands and packaging rather than different hardware. Who it may suit Fitbit Air suits someone who wants continuous health data at the lowest sensible price and does not want a watch. It suits sleep tracking particularly well, because the thing is light and there is no display to glow at night. It suits people already inside Google's ecosystem, since a Google Account and the Google Health app are both required. Important considerations Prices, features and availability change, and several health features are limited by region or age. The figures here reflect Google's own pages on the research date at the top of this pack. Confirm the current terms on the Google Store before buying, especially if a specific health feature or the Premium pricing is the reason you are considering it.
