It was initially created simply to allow me to create a structure to allow me to explain how to build Canvas Power Apps. It then occurred to me that I could use the app to completely replace PowerPoint, and enable me to hold all the points I needed to make as data.
The app also allows me to "manage" the process of introducing a new lesson into the course. The course is free and can be found at www.powerplatformlearn.academy and now stretches to 280+ lessons across 35 modules and runs to an astonishing 42 hours. It's been really tough, and has been my Everest, and is now complete, I've reached the top!
