Cool concept
I tried this app and I like the concept. You can mix numbers, letters, colors and so on. However, looking at the settings it only allows you to let it run for 10 secs max. After those 10 secs are up, the screen turns red and a timer starts running. I let it run for 2 minutes hoping it would turn back to the colors and numbers but nothing happened. This would be the best app if it allowed us to run exercise for an unlimited amount of time instead of 10 seconds.
