Released Guide updated

The Polar Loop is a band with no screen and no subscription. It tracks heart rate around the clock, steps, sleep stages, nightly HRV and Nightly Recharge recovery, and it spots workouts on its own. Everything lands in the free Polar Flow app, which also borrows your phone's GPS for routes.

Where it shines

  1. Sleep

    Sleep stages, a morning sleep score and Nightly Recharge recovery on a light band you forget you are wearing.

  2. Subtle, low-profile look

    No screen, no buttons and no notifications: it tracks quietly in the background.

  3. Battery life

    Up to 8 days between charges and 4 weeks of data held on the band.
