## What is ZenBox?

ZenBox is a sound mixer for sleep, focus, and relaxation. Build your own ambient mix from a library of natural and calming sounds — then let it loop for as long as you need.

HOW IT WORKS
Tap any sound icon to add it to your mix. Tap again to remove it. Long-press an active sound to open its volume slider and balance it against the rest of your mix. Combine as many sounds as you like — rain with a crackling fire, birdsong with ocean waves, whatever helps you unwind or concentrate.
