The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.
Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.
Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
Body Battery, sleep coach, training readiness and VO2 max — the metrics Garmin watch owners rely on — in a screen-free band with no mandatory membership.
Swap between a wrist band and an upper-arm band, which many users find more comfortable during sleep and more accurate during workouts.
Up to 10 days between charges, longer than the Fitbit Air's 7 days. A full charge takes up to 90 minutes on Garmin's proprietary charger.
The right pick depends on what you optimize for.
$409 vs $436 over 3 years.
10 days vs 6 days battery.
6 sensors.
21g.
Health-conscious users on any platform who want continuous stress monitoring (EDA sensor), ECG, and Fitbit's deep wellness coaching — without paying Galaxy Watch or Apple Watch prices. Particularly strong for iPhone users who want serious health tracking at under $250.
Full details →People who want WHOOP-style 24/7 recovery and sleep tracking without a monthly fee, especially existing Garmin users or anyone who wants Garmin's Body Battery and training readiness metrics without wearing a watch.
