This app is perfect for those who are just learning about rhythm and beats in 4/4 timing (using whole, half, and quarter notes). It allows for a simple layering of beats in a great interface which is perfect for someone just starting out. I used it to teach someone who just couldnt get the idea of how beats can be put together in varied combinations to create the basic rhythm heard in many rock, country, pop, and other types of popular music. Wonderful!
No need to "improve" this with complications, except perhaps being able to save and reload compositions.
