Phone placement

Reliable overnight tracking depends on where the phone sits.

Place your phone on a nightstand or the floor beside the bed— not under your pillow or mattress. RESTSMOOTH listens for ambient sound and senses gentle movement through the surface, so a stable nearby surface works best.

Why placement matters

  • Under-pillow placement blocks the microphone and can overheat the device.
  • A nightstand gives the accelerometer a clear reading of bed movement.
  • Keep the charging cable connected if you use combined tracking overnight.

Quick checklist

  1. Phone face-up or on its side on the nightstand.
  2. Microphone unobstructed (no case flap covering the mic).
  3. Arm your alarm, then start sleep from the Tonight screen.
