Full ECG, electrodermal activity stress sensing, SpO2, and continuous heart rate in a tracker thinner than most smartwatches.
Google Maps navigation, Google Wallet NFC payments, and YouTube Music controls — more useful on-device apps than any previous Charge.
7 days of typical use, dropping to around 30 minutes per GPS workout session before needing a charge.
No distractions — WHOOP tracks everything without buzzing, glowing, or asking for your attention. All data lives in the app.
WHOOP's Recovery Score synthesises HRV, resting heart rate, sleep quality, and respiratory rate to tell you how ready your body is each day.
The WHOOP battery pack slides onto the device and charges it without removal — no gaps in overnight sleep tracking.
