--- title: About url: https://koderka.com/about description: I'm Łukasz, a developer in Poland who builds small, private iPhone apps under the name Koderka and writes about how they get made. author: Łukasz --- # About I'm Łukasz, a software developer from Poland. Koderka is the name I publish my iPhone apps under, and this site is where they live. By day I work on mobile apps for other people. Evenings and weekends, I build my own: small, focused apps that do one job well and leave your data where it belongs, on your phone. No accounts unless an app truly needs one, no ads, no selling what you do to anyone. The first app is StopCorn, a private, research-based plan for people who want to quit porn. The next one, howspent, turns photos of receipts into a simple spending record, with the reading done on your iPhone. I build with AI coding tools every day, and I'm interested in where they help and where they don't. That's most of what I'll write about here: how these apps get designed, built, tested and shipped by one person, what worked, what didn't, and what I'd do differently. Real numbers when I have them. If you use one of my apps and something's wrong, or you just want to say hello, write to me at support@koderka.com or through the [contact page](https://koderka.com/contact). I read everything. ## Elsewhere - -
