The Google Fitbit Air is a 12-gram, screenless fitness tracker designed for passive health monitoring, offering core data tracking without a subscription fee, though it lacks built-in GPS and a universal charger, according to testing by Tek.no and TechRadar.
Design and Comfort of the 5-Gram Sensor
Google has stripped away the display entirely for the Fitbit Air, leaving an oval sensor module that weighs 5.2 grams (12 grams total with the band), according to Tek.no testing. The device uses recycled polycarbonate and textile with a stainless steel buckle, secured by small velcro fasteners that reviewers found comfortable for sleep tracking. TechRadar noted the device measures 17 mm wide and is significantly more comfortable to sleep with than a full-sized smartwatch or a Whoop tracker.
App Performance and Free Core Metrics
For the first time, Fitbit has moved away from its legacy app in favor of the Google Health app, which takes about three minutes to set up with a Google account, according to Tek.no. Reviewers highlighted that unlike competitors such as Oura and Whoop, all core health data is free. However, TechRadar described the Google Health app as rörig (messy) and unintuitiv, noting that features are scattered and heavily centered around the AI chatbot Health Coach. Tek.no noted the device sells for knapt tusen kroner, while TechRadar reported it costs 1,190 kronor in Sweden.
Health Tracking, Sleep, and Accuracy
The Fitbit Air monitors heart rate, blood oxygen (SpO2), skin temperature, and sleep stages, utilizing a Gemini-driven sleep model that Google claims is 15 percent more accurate than prior versions, according to Tek.no. TechRadar reported that tracking accuracy for resting and active heart rate closely mirrored the Apple Watch Ultra 3 during testing. Tek.no reported that the device includes passive atrial fibrillation (AFib) monitoring, though it lacks an ECG function. Tek.no noted a minor annoyance: morning data synchronization can take time, and the app requires an internet connection for most analyses.
Fitness Limitations and Battery Life
Neither a dedicated GPS module nor on-board route mapping is included, meaning runners and cyclists must carry a smartphone for connected GPS tracking, according to Tek.no. While daily step and sleep tracking operate smoothly, Tek.no stated that high-intensity heart rate tracking cannot compete with a dedicated chest strap.
