I like the app and the variety of combinations, but I feel there could be some minor tweaks to make it more functional. It would be nice to have the option to control your music volume level separately from the voice commands. Its almost too hard to even play any music to try to hear the commands. Also the rounds play randomly but he speaks the round # which is the set of combinations you are on, but it throws you off on what round you are actually on and how many you have left.
