The current Polar Loop is a screen-free fitness band that discreetly tracks movement, heart rate and sleep without notifications or distractions on your wrist. Built for round-the-clock wear, it brings activity, training and recovery insights into the free Polar Flow app whenever you want to check your progress. Unlike Polar's original Loop tracker, this 2025-generation model has no LED display.

With continuous optical heart-rate monitoring, sleep analysis and automatic activity tracking, the Loop helps you build consistency without needing to start every session manually. It weighs approximately 29 g with its textile wristband, is rated WR30 and offers up to eight days of use per charge. Polar Flow features are available without a recurring subscription; the supplied Polar Charge 2.0 cable supports recharging.

Suggested Use & Compatibility

Wear Polar Loop comfortably around your wrist for day-and-night activity, sleep and recovery tracking. Pair it with a compatible phone running the free Polar Flow app to complete setup, sync data and review your trends; there is no on-device screen for viewing results. The supplied cable is required for charging. WR30 makes the band suitable for swimming, but Polar notes optical wrist heart-rate measurements can be less reliable in water.
