Pulsate is a neat little music app based on the web app called ToneMatrix by André Michelle (creator of audiotool.com). It allows you to use geometry to create melodies straight from your iPhone and iPad. Pulsate’s simple, organic functionality lets you explore a world where sounds and shapes are inextricably linked. Pulsate will keep you hypnotised for hours, you will never make the same melody twice!
Pulsate is available for $0.99
