# WHOOP

Screenless fitness band built around recovery, strain and detailed sleep performance coaching.

WHOOP is a subscription wearable that tracks sleep stages, sleep need, respiratory rate, HRV and recovery. Its sleep coach recommends bedtimes based on strain and sleep debt. Respiratory rate and oxygen trends can be a prompt to talk to a clinician, but WHOOP does not diagnose sleep apnea.

Price: Membership includes the band. Site: https://www.whoop.com/.
