Polar, the brand behind the popular H10 chest strap and Vantage running watches, is challenging Whoop with its own screenless wristband.
Polar is the latest expensive fitness watch brand to add a subscription, and we probably won't have any sub-free smartwatches soon.
Because I'm the editor of Engadget by day and a volunteer coach in my free time, I often get asked which GPS watch or fitness tracker to buy. (People also ask what I'm wearing and the answer is: All of them. I am testing all of them.) For my part, the best running watches are quick to lock in a GPS signal, offer accurate distance and pace tracking, last a long time on a charge, are comfortable to wear and easy to use.
