Independent developer · Hamburg

Small, focused apps for iPhone, iPad and Mac.

I'm an independent hobby developer from Hamburg. Four apps on the App Store so far — from a license-plate lookup to a mathematical arcade racer. No trackers, no ads, just things I wanted to exist.

Behind the apps

One developer, four apps, zero venture capital.

App development is my hobby, not my day job. I design every icon by hand in Procreate, write the code in Swift and SwiftUI, and ship when it feels right. If something here turns out to be useful or fun, that's the whole reward.
