In a class project, we designed an app focusing on a single point of interactivity. I designed a running app that plays music to match your running speed. The interactivity is the user and the speed at which they run.
I used Figma to create the interface, and it was my first time using it. The process was a lot of fun and I picked it up pretty quickly. I created the main version for a phone as well as a few frames for a smartwatch version.
