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.
Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
