Ray or Polar Loop?
Two screen-free bands with no subscription. One charges from a cable, the other from light.
Polar Loop is a $169.99 screen-free band from Polar. Like Ray, it has no display and needs no subscription, so the choice comes down to what you want it to do. Loop leans on Polar Flow's workout and recovery analysis and lasts up to eight days per charge. Ray focuses on everyday health tracking and runs on light.
The short answer
Choose Polar Loop if you train seriously and want Polar's established workout and recovery analysis at a lower price. Choose Ray if you'd rather never charge your tracker and want a lighter band that can look like jewelry.
Polar Loop status: Currently sold.
Side by side
Specs are manufacturer claims and US pricing snapshots, not lab-test results. A blank promise is less useful than a clear tradeoff, so we keep this list deliberately practical.
