    App is very simple and does the job. Adding scales would be appreciated.
  • Great learning tool.

    By SnookFan
    This is a great way to learn the fundamentals of music theory. I use its companion app Tenuto to practice what I learn. Very highly recommended.
  • Please add more audio !!

    By Ed15
    Great app but please add more audio examples. For instance, I am trying to learn more about compound meters or odd meters and there are NO audio examples !! Frankly I am a little annoyed coz that’s why I bought it. Otherwise it’s a nice app.

    Great job. Covers the basics. A wonderful refresher and learned some new material as well. Having dabbled at coding, what a beautiful, refined piece of work. A keeper reference tool.

    I am majoring in music ed at my college and this app is so helpful especially that my note taking is horrible. This app is super helpful and highly recommend it for those taking theory in college
  • Outstanding but...

    By TheReluctantReviewer625
    ... needs to incorporate guitar theory, not just theory demonstrated on the piano board. Where is the Circle of Fifths?
  • Missing a lot

    By 1 Al
    Where’s is the circle of fifths?
  • Practice?

    By galaxykennie
    The Music Theory website directed me to this app as one of the things for practicing, but there’s nothing for practicing notes, keys, etc. on the app - only explanations. I’m a bit disappointed in it.
  • Solid foundation

    By doormang
    What can I say, this app is clean and easy on the eyes. Excellent as reference when you forget things, and as a learning tool the way it moves the explanations with visuals and corresponding sounds is very logical, also makes it easy to understand the lessons.
