WHOOP
WHOOP makes a screenless, button-free wrist band (WHOOP 5.0, and WHOOP MG with an FDA-cleared ECG) that tracks strain, recovery, sleep and health metrics. Its customers range from professional athletes to ordinary consumers. It makes its money from annual memberships: the band ships as part of the membership and stops tracking without one. Australia has been the exception since May 2026, where the band is sold separately but still needs a subscription. It also sells add-on services such as Advanced Labs blood testing.
