Rare combination: a bright always-on AMOLED display and 14 days of typical use without charging.
Medical-grade ECG and bioelectrical impedance body fat analysis — features usually found only on watches costing $100–$200 more.
Zepp Coach uses Amazfit's AI to build personalised workout plans, recovery recommendations, and stress management guidance.
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.
