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.
The 46mm Apex 4 delivers 65 hours of GPS tracking and 24 days typical use — enough for multi-day mountain events without charging. The 42mm offers 41h GPS and 15 days.
Global topographic maps with instant rendering, turn-by-turn navigation, POIs, and an underwater depth gauge — the Apex 4 is the first COROS mid-tier with a depth sensor.
Audio alerts, hands-free calling, and voice pin recording — a first for the Apex line, adding practical trail and daily-wear convenience to this mountain sports watch.
