About

Hi, I’m Holger.

I’ve been building apps since 2009, with my first App Store release in 2010. By day I’m an aerospace engineer; in my spare time I build the kind of software I want to use myself.

The name Extremely Successful Apps is a little playful. The work is serious: useful native software, local-first where it matters, and made by a person rather than a marketing department.
