ApplicationsTycha — falling asleep
Tycha — falling asleep
An app for falling asleep: its six sounds are not recordings but maths computed live, so the mix never repeats and never starts to grate.
What it is
Every sleep app is built on audio files: rain, wind, a campfire. A file is finite, so it loops, and any loop stops being background sooner or later — by the twentieth minute the ear is waiting for the seam and wakes up on it. Here six sounds are synthesised by maths in real time: the mix has no beginning, no end and no repeat point.
The rest is built around the sound: a 4-7-8 breathing circle, a sleep report drawn as a starry sky instead of bar charts, and an advisor that explains why a night went badly instead of scoring it out of a hundred. A score changes nothing in behaviour; the sentence “yesterday you went to bed two hours later than usual” does.
Specifications: Flutter — one source tree gives both Android and Windows; the Android package is built. There is not a single audio file inside, so the app is small and sounds the same at any volume and any length. The synthesis runs on the device itself, with no network.
