iPhone
Blend rain, fire, birds & more into your own calming mix. Tap to toggle, long-press for volume, set a sleep timer, and drift off or lock in on focus.
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.
