After getting the MVP to work, I knew I had to figure out a few things to make it more useable. Mainly simple audio cues and keeping the screen to stay away while the 7 minute exercise is going on.
This was actually not as difficult as I thought. True it did take time because I'm still very green with programming, but I accomplished what I wanted.
I've done at least a half dozen workouts using the app and it's exactly what I wanted. I know a few others have tested it out and enjoyed it. Puts a smile on my face!
