Apps, games and long-term projects

My projects range from practical everyday apps to my large-scale football manager in closed development, currently known internally as FootSim. Three Android apps are available for free testing; Dailumo is a macOS project in development.

FootSim

A football manager built for the long term.

FootSim is my large-scale football manager project. It takes up a substantial share of my development time and goes well beyond a single everyday app.

I am building a game that brings together football, strategic decisions and long-term club development.

My approach to everyday apps

Real problems first

The starting point is always a recurring situation from everyday life or operations.

Local-first thinking

Personal data should stay on the device wherever the product allows it.

Control remains visible

Automation should help without hiding important decisions.

Choose the app that fits your day.
