I loved the app! I had absolutely no issues with it and found no bugs. The user interface has been done very well and I enjoyed the "tap to set own speed" feature. It accents the first note of every bar and keeps count of the number of bars. Being able to set the bar Im on would be nice but that isnt an issue. I find its design easy to use and I knew what to do with no help right from the start. Id definitely say well done to the developers!
