Why data-led trackers run Whoop and Fitbit Air together

Whoop reads recovery and strain and turns it into coaching. The Fitbit Air covers the broader daily picture inside the Fitbit app.

People who trust one for sleep and the other for activity, or who are comparing both before committing, end up wearing two bands. Smartlet carries both on a single wrist instead.
