Im a 40 something musician, have played for enjoyment most of my life and never taken advanced music theory. I love this app and use it daily but its going to take a lot of practice before I can use many of the features. I wish there was an option to reduce the number of measures for the rhythm and dictation exercises and a feature to turn off the timer. The same goes for the chord progression exercises. An option to start with two or three chords instead of two measures and remove the timer would be helpful for users just starting out. Thank you.
