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
- Adjustable delay
- Shake to clear
- Evolve when idle
- Sleep Timer

Recommended for headphones or external speakers.

One of the first apps you ever downloaded is still strong

SeanDykhouse on

After watching games, music, entertainment, and social media come and go, it is encouraging and exciting to come back to this work again and again. Highly recommend this one.

Years later, still enjoyable

This is such an underrated app. Bloom is lovely, peaceful, contemplative. A hidden gem. Do yourself the favor of downloading it.

:) That moment ...

That moment when you realize Bloom can make chords :)

The sounds are too limited.

I downloaded several generative music apps. Bloom was one of them. Unfortunately the loan was a paid app right off the bat where as the others gave trials. The app that I downloaded and like the most is and Endel. Endel is much more complex in the sounds that it generates in the textures that it creates. I find Endel much more enjoyable to listen to then Bloom. Bloom is very sublime, and generates an ambience rather than an engaging musical exploration or experience.

greatest music app

Our babies play Bloom, and so do their m&d.

Please give option to remove the self-advertisements??

I’ve been a fan of Bloom for 9 years. I wish SO much there were a way I could revert to a version where you don’t see the ad on the initial screen for the other apps by the same people. For me those ads, even though they’re small, are so distracting and against what I think the spirit and experience of Bloom should be. It’s frustrating. Please give an option not to see them - I would pay for it!

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.

12/9/2017 Update.

I am blown away with this app! Loads of potential here as well. Eno is one of my fav's, so it's a must to get! Should hold me over till Rjdj. 12/9/2017 Update. Still one of my favorite generative apps, but it desperately needs to be updated to iOS 11 because it crashes frequently now. Very frustrating because it’s a one of a kind app. Hopefully the developer hasn’t abandoned it. Do not purchase unless running iOS 10 or lower.

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.
