Ambient Light:
Dreaming Fox uses your phones screen to illuminate the room with soft natural colors.
Use them as alternative to bright room lights.

A timer will slowly dim the light and the music while you fall asleep, otherwise the sleep sounds will continue and help you to sleep again if you wake up at night.

But if you don't find the way to bed, Dreaming Fox contains a flashlight (led light) to lead you way. :)
