Beat Doctor analyzes the tempo of the music that it hears in real time as well as songs from your music library. Beat Doctor draws a bar chart showing how the tempo of the music varies over time. You can play back and zoom in and out on the chart. Use Beat Doctor when practicing to see how steady your tempo is, or use it to get a reference tempo of pre-recorded music. Beat Doctor does a pretty good job of guessing tempo, but it can get easily confused as well. Use Settings to adjust parameters of the tempo detection algorithm. Have fun! Like all my apps, Beat Doctor will never collect any information from you or show you advertising of any kind.
