Why Galaxy Watch owners add a Whoop

The Galaxy Watch runs the screen, the apps and the Samsung Health picture. The Whoop runs silently in the background, reading sleep, recovery and strain.

Worn together they usually mean two bands. Smartlet carries both on one wrist, the Galaxy Watch outer, the Whoop inner.
