Garmin Cirqa review: A fine but utterly inessential smart band

Garmin’s Cirqa is a screenless, one-ounce fitness band that tracks 24/7 heart rate, respiration, stress, activity, sleep, menstrual cycle and temperature, delivering accurate automatic activity detection but lacking GPS and advanced AI insights. It uses a single button and a proprietary USB-C charger, offering a 10-day battery life, but its minimalist design serves more as a status symbol than a functional rival to Whoop.
