Google introduces the screenless Fitbit Air, a health-and-fitness wearable designed for continuous monitoring rather than on-device viewing. The device is positioned to compete with screenless trackers such as Whoop, which focus on passive data collection and long-term tracking. Fitbit Air includes ongoing measurements including 24/7 heart rate monitoring and heart rhythm monitoring, with alerts intended to flag possible atrial fibrillation (Afib). It also tracks oxygen saturation (SpO2) and provides metrics such as resting heart rate and heart rate variability. For recovery and sleep insights, the tracker measures sleep stages and sleep duration. Overall, the Fitbit Air reflects the broader shift in fitness wearables toward 24/7 health data collection, using sensors to monitor key physiological signals throughout the day and night. The available reports emphasize the device’s feature set and its role in the growing category of screenless, subscription-style style health trackers.
