The Music Box for iOS

Lullabies, traditionals, children's songs and classical music.
Make your iPhone the most versatile music box in the world.


Real sounds & performance.

The unique playback engine allows zZzBOX to perform every single play-through of a song individually, always a bit different & fresh!

  • Every single sound has been multi-sampled carefully in a high-quality recording setup with a boutique instrument. On top of that, there are two completely different sound sets to choose from.
  • But there’s eye candy, too! 3 different playback visualisations animate each note in real time: Watch the cylinder and comb do their magic, just like a real music box!
Flexible Key

Play an instrument or sing along? Change the key of a song to your liking, the playback will instantly adapt!

Variable Tempo

Adjust the tempo of the song at any point during playback. Since the audio engine performs in real time, the sound quality will stay exactly the same!

Sleep Timer

Set up a sleep timer with your preferred duration. After up to 4 hours the audio playback will be stopped.

Fade Out

Optionally, let the sleep timer fade out the volume and decrease the tempo of the playback gradually. Perfect to put your little ones to sleep.


Shape sound & playback timing

Customize your music box even further by tweaking the advanced settings!

  • Switch to octave mode for the broader, more orchestral sound of a 72-note boutique music box.
  • Switch to mellow sound for a softer timbre with less trebles.
  • Tweak the resonance to change the length of the notes. A smaller value resembles a music box with a smaller body.
  • The arpeggiation of chords is a characteristic musical means of music boxes. To make every performance unique, arpeggiations are executed slightly different each time.
  • A subtle rhythmical offset between the musical voices can be introduced to resemble the slightly choppy playback of common music boxes.
