Google Fitbit Air - Smart Health Tracker

All-Day Health Tracking With AI-Powered Coaching

The Google Fitbit Air is built to disappear on the wrist while working around the clock. A lightweight, screenless design carries advanced biometric sensors that continuously track heart rate, sleep stages, blood oxygen and skin temperature, so daily wear stays comfortable through workouts, sleep and everything in between. At just 5.2 grams for the device itself, it's designed to be forgotten while worn and relied on when it matters.

Gemini AI and Google Health turn that raw sensor data into coaching that actually adapts — sleep guidance, readiness scores and training suggestions shift based on real behavior rather than a fixed plan. Cardio Load tracking and AFib detection during rest add a layer of health monitoring beyond basic step counting, while Sleep Score and detailed stage tracking give a clearer picture of recovery night to night.

Up to 7 days of battery life keeps the Air out of the charger most of the week, and a 5-minute fast charge covers a full day when time is short. Water resistance to 50 meters means it can stay on through showers, swims and sweat without a second thought.
