App development — practical and focused

The best apps solve one real problem well. The most expensive failures tried to solve ten at once. I build the first kind — and say so honestly when an app is not the right answer.

What you get

A focused app — web app or mobile — that does what it promises, also after version one. Built with modern, proven technology and the same attention to accessibility and maintainability as all studio work.

ErfPlan, the studio’s own property-map app, shows what that looks like: local-first, no account needed, built to last years.

How it works

First, sharpen the problem — the first version often turns out smaller than expected, which is good news for your budget. Then a working prototype, real use, and only then expansion based on what proves to work.

No months of silence followed by a grand reveal. You see every step.

What it costs — honestly

Apps are serious work: a focused first version starts around € 5,000, and the market prices full-scale apps at € 15,000 to € 50,000. The honest answer is often: start smaller than you think.

That is why every app project starts with a short, affordable discovery: problem, approach, and a realistic figure on paper — only then do you decide about the build.
