Paul Rybarczyk

My name is Paul, and I created a Mac app called iRunTrains as a hobby-project back in 2010. Later, I also teamed up with a friend to bring iRunTrains to his iPhone/iPad App Store. Although both those projects have gradually slowed over the years, I’m now retired and I’ve jumped back on the development train! So in 2025, I started rebuilding iRunTrains from scratch as a modern 3D web application (https://iRunTrains.com).
