Why athletes pair Apple Watch with Whoop

The Apple Watch runs the screen, the notifications and the apps. The Whoop runs silently in the background, reading sleep, recovery and strain.

People who want both usually wear two bands and live with two tan lines. Smartlet carries both on one wrist, the Apple Watch outer, the Whoop inner.

Questions

Frequently asked questions

  • Can I wear an Apple Watch and a Whoop at the same time with Smartlet?
    Yes. Both are Smartlet-compatible, so one strap carries the Apple Watch and a Whoop 5.0 or MG together on a single wrist.
  • Which Whoop models work with Smartlet?
    Whoop 5.0 and Whoop MG are compatible. Whoop 4.0 is not supported.
  • Will my Whoop and Apple Watch sensors still read correctly?
    Each device sits in its own position, one on top of the wrist and the other underneath, against the skin. Manufacturers do not certify readings taken in these positions: for a reading with medical weight, put the device back on its own band and follow the manufacturer's instructions.
  • Does Smartlet modify either device?
    No. Mounting is reversible and leaves both devices unchanged.
