Moonrain

Moonrain is a calm, offline sound mixer for sleep, relaxation, and focus.

Open the app, tap play, and drift off to rain on the window, ocean waves, a crackling fireplace, or deep brown noise. Mix up to four sounds with independent volumes, save your favorite combinations, and set a sleep timer that fades everything out gently after you fall asleep.
