Windows tools designed to do their job really well.
Hi, I’m Christian. I develop software for tasks that make me think: there has to be an easier way.
My tools run locally on your computer, require no subscription, and don’t force you into the cloud for every little thing.

I ask myself that question with every new project.
I don’t build a tool just because it is technically possible. There has to be a problem that annoys me, a process that is unnecessarily complicated, or something missing from an existing solution.
Then I start building.
“The software should be easy to understand, perform its core task well, and impose as few restrictions as possible.”

I build the tools I would want to use myself.
I’m Christian Rüsken and I have been developing software for many years. My applications should solve a task clearly, without accounts, subscriptions, or unnecessary features.
