Whoop is a screen-free band that tracks sleep, strain, recovery and heart data around the clock, with coaching built on top. Memberships span the 4.0 band through the MG with ECG and blood-pressure insights. Worn by Cristiano Ronaldo and Nelly Korda.
Whoop is the odd one out in this category: it doesn't plan a single workout. It's a screen-free band you wear around the clock, and its job is to tell you what your training is doing to your body. Sleep, strain, recovery, stress and heart data get collected every second, and the app turns that into a daily verdict: you're recovered, push today, or you're run down, back off. The coaching layer speaks plain language, answering questions about your own data rather than dumping charts on you.
The company's membership model bundles hardware with subscription. The entry tier ships the WHOOP 4.0 with five-day battery and the core sleep, strain and recovery insights. The Peak tier moves to the 5.0 hardware with 14+ day battery and adds a health monitor, stress tracking, and longevity features the company calls Healthspan and Pace of Aging. The top tier, built on the medical-grade MG band, adds ECG readings, irregular-rhythm alerts, and daily blood-pressure insights. A free trial exists, and the athlete roster wearing it (Cristiano Ronaldo, Virgil van Dijk, Nelly Korda) is real sponsorship, not stock photos.
No screen means no distraction: it's a sensor, not a watch arguing for attention. The recovery score gives hard training structure. Whoop's own numbers say daily wearers add 91 minutes of weekly activity and 2.3 hours of weekly sleep; treat those as marketing, but the direction matches what users report.
It's a subscription forever, it tells you nothing about what exercises to do, and if you train twice a week for general health, a recovery score is solving a problem you don't have. Pair it with a planner like Fitbod or Athletica, which is exactly how most serious users run it.
The best recovery data money can buy on a wrist. For hard-training people it's the missing half of every workout app; for casual exercisers it's an expensive way to be told to sleep more.
