GET MORE ACCURATE DATA

5 LEDs and 4 photodiodes capture your data more often than most wearables, providing best-in-class accuracy validated in lab studies and with third-party testing.

TRACK METRICS 24/7

Wirelessly charge your WHOOP with a waterproof* battery pack and capture data continuously—even while in the shower or washing dishes.

BEHAVIORAL JOURNAL
