Helpful! – Music Tutor (Sight-reading) Review

I really enjoy this application and it has improved my ability to recognize notes for sure. However, I wish there were just a few more options. For example, I like that at the end of a session I can study my incorrect notes. But why can’t I launch another session where I can really hammer those home? Perhaps have an option to weave frequently missed notes into a new session? Also, why no landscape mode?
