Great app!
One of the coolest things about this app is its range of audience. For someone who knows nothing about music, its a fun app to mess around in and have fun, while someone whos taken years of music theory/songwriting classes can create advanced music to their liking as well. This is due to having a great, easy to use, and simple interface while simultaneously having many advanced and complex options. If youre serious about music, get the pro version. 10$ seems expensive for a mobile app, but for a music making program with this amount of quality, its super cheap. Of course, it has its flaws, such as no ability to queue changes like tempo/octave/effects and that if you want to use accidental you have to switch to a chromatic scale (or a custom scale), but Im sure features are still being added, and if not most of these are problems that you can get around pretty easy.
