Set up this speaker
One tap arms this device. After that your phone controls it remotely.

Before you leave it
Tick each once you've done it — these keep the sound alive overnight. (Advisory; you can arm anyway.)
Place it across the room — at least 2 m away, never in or on the crib. Keep the volume low: louder isn’t safer, and no app can measure the real loudness at the crib. Playback winds down after 45 min by default — gentler than all night.
If iOS ever stops the sound, this screen goes dark with “tap to resume”.
