evo.com | Garmin Computers > The Garmin CIRQA Smart Band skips the screen entirely, betting that you don't need another display buzzing on your wrist to actually understand your body. Strap it to your wrist or upper arm and it quietly runs 24/7, tracking sleep stages, HRV, Pulse Ox, skin temperature, and Body Battery energy levels while auto-detecting more than 80 activities with a single tap of the side button. At 20 grams with a claimed 10 days of battery and zero subscription required, it's a low-effort way to get real data on how you're actually recovering, whether that's after a long trail run or a rough night's sleep.
