Google Fitbit Air is a lightweight health and fitness tracker designed for users who want continuous wellness insights without wearing a bulky smartwatch.
Its strongest selling point is not only the slim design. The real advantage is the combination of 24/7 health tracking, sleep insights, readiness guidance, Gemini-powered coaching through Google Health Premium, and up to 7 days of battery life in an ultra-light wearable.

AFib Monitoring Support
The tracker can monitor heart rhythm while the user is still or sleeping and look out for signs of atrial fibrillation.
Sleep Score and Sleep Stages
Advanced sleep tracking helps users better understand sleep quality, sleep patterns, and sleep stages.
Readiness Score
