Score / 10
WHOOP · Recovery Tracker
A screen-free recovery band that is really a subscription service. The hardware is a delivery mechanism for daily strain, recovery and sleep analytics that lean athletic.
Verdict
Best for athletes who want a coach in a band. Not for users who prefer a screen or resent subscriptions.
- Sold direct as a membership — marketplace listings are usually resellers.
Price
No upfront hardware cost — membership from roughly £229/year
Subscription
Required (hardware is free with membership)
Battery
14 days (5.0)
Waterproof
10 m
How it works
PPG samples 100 Hz overnight for HR and HRV, temperature and SpO₂ track illness and altitude, and accelerometer plus HR fuse into a proprietary 0–21 strain score. Recovery is calculated at wake from HRV, RHR and sleep quality.
Sensors
- PPG for HR/HRV
- SpO₂, skin temperature
- 3-axis accelerometer
- ECG (5.0 MG add-on)
Metrics tracked
- Recovery score (HRV, RHR, sleep, respiratory rate)
- Strain score (cardiovascular load 0–21)
- Sleep stages, sleep debt, sleep consistency
- Journal-based behaviour correlation
- Menstrual cycle coaching
Strengths & weaknesses
Strengths
- Coherent recovery ↔ strain ↔ sleep loop that changes behaviour
- Excellent sleep and HRV trend data
- Wearable in the shower, gym, bed — very high adherence
- Journal correlation surfaces personal patterns (alcohol, late meals, etc.)
Weaknesses
- You do not own the data pipeline — cancel the subscription, lose the app
- No screen; you cannot glance at HR mid-workout
- GPS piggy-backs off your phone
Who it's for
Best for
- Athletes who train hard and need objective recovery guidance
- Users who want automatic behaviour correlation instead of manual analysis
Skip if
- Anyone who wants to own a device and avoid recurring cost
- Users who need a smartwatch's notifications and screen
Data quality
HR accuracy at rest and low intensity is strong; less reliable during heavy weightlifting or intervals where PPG is confounded by muscle contraction. Sleep-stage agreement is comparable to leading rings.
Ecosystem & privacy
First-party WHOOP app, Strava sync, Apple Health / Google Health Connect exports, growing team and coach features.
Data stored on WHOOP servers; users can export CSVs and delete accounts. Membership fees fund infrastructure, not data resale.
