Bloom

Bloom is a generative ambient music app created by Brian Eno and Peter Chilvers for iPhone and iPod touch. Part instrument, part composition, and part artwork, it lets you sculpt intricate patterns and melodies with a tap, while a built-in generative player evolves when idle to produce an endless library of music and visuals.

Features include 12 mood settings, random mood shuffle, adjustable delay, shake to clear, idle evolution, and a sleep timer. Designed for headphones or external speakers, Bloom has earned praise for its hypnotic, relaxing approach to ambient sound.
