What others say

It's completely awesome. And kind of surreal. An experience that it's not easy to describe in words.

Federico Viticci, MacStories

This app is transformative and cutting edge. We don't say this often but this is a must have app that we enthusiastically endorse.


If you've ever consumed psychedelics, the auditory effects in some of the scenes are very similar to the time-slipping, inverse cascading repeats that can be provoked by some chemicals.

Joel Johnson, BoingBoing Gadgets

Hey, it's mushrooms without the mushrooms!

John Mahoney, Gizmodo

Where other apps provide listless minigames, boring photo galleries and jargon-filled text, this one provides something of an experience.

Mark Brown, Wired UK

Voyager reimagines music listening not in lists of tracks or grids of beats, but in the liquid, alien landscapes of your dreams.

Peter Kirn, Create Digital Music
