Whoop Band One 5.0 Sensor

A screen-free fitness and recovery tracker worn on the wrist, focused entirely on giving you deep insight into sleep quality, recovery, and daily strain rather than notifications or apps. The Whoop 5.0 sensor brings improved sensors and battery life over previous generations, delivering more accurate heart rate, respiratory rate, and sleep stage tracking. Since it has no screen, it’s genuinely comfortable for 24/7 wear, including overnight, without the distraction a smartwatch display might bring.
