Google Fitbit Air
Overview
The Google Fitbit Air is a screenless fitness and health tracker that weighs just 12 grams with the band, making it Google's smallest, lightest, and most affordable wearable. Designed for continuous 24/7 wear, it tracks heart rate, blood oxygen saturation (SpO2), skin temperature, sleep stages, HRV, and activity with advanced optical sensors and a 3-axis accelerometer/gyroscope. Powered by Google's Gemini AI through the Google Health app, the Fitbit Air delivers personalized health coaching, AFib alerting, and detailed sleep analysis at $99.99 with no required subscription — positioning it as a direct competitor to Whoop and Oura.
