How Keely compares.
The Polar Loop with Keely is a way to get recovery, training load, stress and sleep scores without a subscription. These pages compare it with WHOOP, Oura and Polar’s own app, Polar Flow: what each costs, what each measures, and what each does that Keely doesn’t.

The comparisons
How we write them
- Facts come from the source. Everything about another product comes from its maker’s own pages, with the date we checked. Prices and features change, so check theirs before you buy.
- Fair both ways. Each comparison says where the other product does more than Keely.
- Names, not endorsements. We name other products only to compare them. Keely isn’t affiliated with or endorsed by WHOOP, Oura or Polar.
