Pretty basic for a paid app – Salsa Rhythm Review

Sure, this app provides modifiable tracks to suit your needs. But, that’s absolutely it. Pretty much as bare bones as you can get. I was hoping for a) tutoriels and some instruction/ information, b) some pre-made tracks that you can just select and play with adjustable timing, and c) there is a functionless goggle switch that seems to control nothing at all. So, some more information and guidance would be useful.
