About
Small studio. Real products.
Heijnes Digital is a one-person app studio based in the Netherlands. Every app is designed, built, and shipped by hand — no outsourcing, no templates, no fluff.
We use AI where it genuinely helps: personalized advice, content generation, pattern detection. Not as a buzzword, but as a tool that makes each app meaningfully better.
