Sing your own lullaby
8 gentle songs, from Nightfall and Soft Calm to Golden Wave and Air Drift.
Record yourself singing a lullaby or shushing, or import an audio file, and mix it with the other sounds.
A soft night light
Place your phone on a table with the screen facing the ceiling. It gives off a dim glow that slowly rises and fades like waves. Adjust the brightness for a big or a small room.
Fades out gently
Set a sleep timer and the sound fades out smoothly instead of stopping abruptly, so nobody's startled awake. Choose 15, 30, 45 or 60 minutes.
Save your favorite mixes
Found the blend that works? Save it as a mix and play it back instantly next nap time, no rebuilding from scratch.
Plays through the night
Keeps playing in the background and with the screen locked. Pause or resume from the lock screen.
