Evolve

Every idea starts the way it looks over there — a sloppy sketch to anyone else, a starting point to us. This one turned into SubSonify, a music app for people who run their own server.

A hand-drawn sketch: a phone screen labelled "her superpower" and a window of code labelled "his superpower".

About us

He → logical, stubborn, writes code without looking at the keyboard, sometimes too funny and afraid of spiders.

She → always misspelling words, reads 4 books at the same time, almost always happy, dreams a lot and stutters when nervous.

Combine those things and you see that our workflow goes with ease and fun =)

What we make

SubSonify

A native iOS app for anything that speaks the Subsonic API — Navidrome, Airsonic, Ampache, gonic. Point it at your server and you get a real music app on the phone, in the car and on the watch.

We built it because the apps we tried treated our own server as an afterthought. SubSonify works the other way around: the library lives on the device, downloads survive bad networks, and none of it needs an account with us.
