First-night setup

Wear the ring the first night you have it, on the index finger of your non-dominant hand, and keep the app on the phone you sleep near. The ring records overnight on its own and stores seven days of samples, so it does not matter if the phone is in another room.

Sleep staging tunes itself to you after seven nights, and the recovery score needs a fourteen-day baseline before it settles. Early nights are still recorded; they read as a wider range than later ones.
