Polar

Polar may be best known for its heart rate tracking solutions, but it also makes an array of wrist-worn activity trackers, sports and smart watches (powered by wearOS), and even a smart/connected scale. In addition to selling to end users, the company also offers corporate wellness programs that are designed to reward employees for their efforts in leading a physically active lifestyle.
