Developed by ambient pioneer Brian Eno and musician / software designer Peter Chilvers, Bloom explores uncharted territory in the realm of applications for the iPhone and iPod touch. Part instrument, part composition and part artwork, Bloom's innovative controls allow anyone to create elaborate patterns and unique melodies by simply tapping the screen. A generative music player takes over when Bloom is left idle, creating an infinite selection of compositions and their accompanying visualisations.

"Bloom is an endless music machine, a music box for the 21st century. You can play it, and you can watch it play itself." - Brian Eno


- 12 different mood settings
- Random mood shuffle

One of my all-time favorite apps


Bloom represents a brilliant fusion of Brian Eno's ideas about "generative music" with the computing power and mobility of an iOS device, courtesy of software designer Peter Chilvers, a fine composer in his own right. It was innovative when it was first released several years ago, and thankfully Chilvers has now updated it to be compatible with iOS 10.

You could regard this as a sort of infinite album: a software engine that you can either customize or leave to its own devices, which will endlessly create a kind of music that Eno has, at different times, called ambient, generative, and "thinking music." The music never exactly repeats itself, though of course it's restricted in other ways by the specific design of the software and the limited number of sound-types available. If you've ever enjoyed the work of Eno and others in this vein, I highly recommend Bloom.

Essential app


I’ve had this app since it’s release and use it almost every night to help calm down before falling asleep. The generative music and it’s programmed forever changing order is both soothing, the almost repetition leading to a sort of gnosis.



At first I thought this app was kinda cool, but more of a curiosity when I was bored and bought/installed it while laid over in the airport. I played around with it for a bit... and got this very strange feeling I was "playing" with something completely new. I've never interacted with anything quite like this before. Thus far, this has to be the most innovative... creative... relaxing... inspirational.... app I've downloaded to date. Would buy it again in an abstract heart beat.

For the next version, I'd like to see a way to either select a different base sound, or a way to alter it's freqs. And, it'd be nice is the basic artwork created varied more than just circles.

Still, the genius of this app in part is it's simplicity and intuitive use. Makes me wonder why I was always so enthralled with ambient, minimal music compositions when it's soooo easy to make your own. ;-)

(warning: after awhile... I thought the app wasn't working right. I could no longer hear the lower tone sounds from the iphone. I tried everything to try and fix it, ie. reinstalling, rebooting, and even restoring. Then, I realized when I was first playing with it in the airport I was using my headphones. Some of the lower pitch tones aren't quite audible with the little iphone's speakers. But with headphones, or hooked up to a stereo.. the audio quality is very good at all pitches.)
