Android apps built and run by one person — design, client, server and everything in between.

Apps

Luma — Ai Chat

Coming soon

Chat with AI characters: thousands made by other people, or your own. Every reply is generated on the spot, so no two conversations are alike. Create a character in a few minutes, publish it, and see how many people talk to it.

Fret

Coming soon

Chords and lyrics for guitar, laid out so you can actually play along: clean chord sheets, search by song or artist, and your own versions of the songs you know differently.

Decks for HS

On Google Play

Hearthstone deck lists with card details, filters by class and format, and offline access to the decks you save.

About

I am Andrii Maltsev, an Android developer based in Germany. I build the whole thing myself: interface in Kotlin and Compose Multiplatform, backend in Kotlin with Ktor and PostgreSQL, running on my own server.

The apps here are the ones I keep working on. They are small on purpose — a single clear job each, no accounts you do not need, no data collected for the sake of it.
