Whoop

Whoop is the screenless fitness tracker that makes you pay $239 annually to stare at your data instead of staring at a screen, and honestly? That kind of restraint is rare in wearables where everyone else is basically selling you a tiny computer for your wrist. They just raised $575 million at a $10.1 billion valuation in March 2026, which means investors still really believe in the subscription model — and honestly, after seeing how many people actually use their Whoop consistently, I get it. It's not for everyone, but for the people who are actually serious about recovery and strain tracking, it's apparently the move.
