Carlo Maryska

Indie iOS developer · Germany

I design and build iOS apps with a soft spot for the details that make software feel right: motion, typography and interfaces that feel alive. Besides that, I love tinkering with AI and seeing what new things become possible.

Four of my apps are live on the App Store. They're lying on the desk below.
