It all started with the substitute timetable at my old school, where you had to find your own entry in one very long list every time. That is what I learned Swift on.
In a statistics lecture it struck me that daily body weight fluctuates exactly like measurements in a study. That became Scelta, together with a pinch of playful motivation. Since 2023 it has also been on Android, built with Christoph Pferschy, the developer of Hydro Coach.
Treeceps came out of my bachelor thesis on gamification: a fitness world where your steps feed the animals and your achievements make flowers grow.
I took the training side of Treeceps further and released it as an app of its own, built entirely around strength training.
Then came a water temperature tracker for the Apple Watch, for ice bathing, the favourite lake and every dip in between.
And a Mahjong in honour of my grandfather, who loved the game so much.
