What it does it does well – Rhythm Sight Reading Trainer Review

Doesn't do a ton... Just gives you exercises and provides immediate feedback as to how you did. However, if you're dedicated, and you work with this, it can really improve your reading ability. It would be nice If the exercises were broken up in to categories, or there were some way to choose how you were approaching various trouble areas... Maybe in an update? For $2.99 this is a very good app.
