About Lull
Lull is a calm, private sound mixer for sleep, focus and finding a little quiet. Layer sounds, set the volume of each one, and start a sleep timer that fades everything out. Mixes can be saved and sounds are searchable. It keeps playing with the screen off, and your mixes and imported sounds stay on your phone.
