I found an old demo of an app I worked on around 2010. Based on an earlier C++ Palm application, this version was written in C#/Xamarin as a cross-platform mobile project.
It brings back fond memories of hacking away to The Resistance by Muse. The same period also included a Twitter client, a professional calculator, and several games.
This page is a historical demo, not a current product-availability notice. Panoramic Software is still active in 2026, but its current product catalogue no longer lists Guitar Suite among the featured applications.
What remains interesting to me is the development context: cross-platform mobile work long before today’s frameworks made shared UI and business logic feel routine. The tooling changed; the trade-off did not. Sharing code across platforms still means deciding carefully where platform-specific behaviour belongs.
