The Google Fitbit Air is a screenless health tracker built for people who want continuous health monitoring without the bulk or distraction of a smartwatch. At 12 grams with the band and just 8.3mm thin, it sits quietly on your wrist throughout your day, your workouts, and your sleep without asking anything of you.
The screenless design is intentional: the tracker collects your health data continuously, and you review it whenever you want through the Google Health app on your phone. It monitors heart rate around the clock, measures blood oxygen levels (SpO2), tracks your sleep stages with a machine learning model that delivers 15% more accurate results than the previous generation, and checks for signs of atrial fibrillation (AFib) — a feature rarely found in trackers at this level.
The Google Health app transforms that data into actionable guidance through an AI-powered health coach built on Gemini, giving you personalised fitness and sleep plans based on your actual metrics. Battery lasts a full week on a single charge, and the tracker is water-resistant to 50 meters, compatible with most Android and iOS devices.
