Compare fitness trackers
The deciding difference in this category is usually not the hardware. Garmin Cirqa and Fitbit Air are bought outright; WHOOP publishes no standalone hardware price at all and is sold as a membership. Put them side by side on ongoing cost, battery life, sensors and where on your body they sit.
