I read a few reviews about the app not being easy to use. I dont know how you can make it much easier without adding a robot voice to read the other characters for you.
My wife reads the second character parts, so it doesnt feel like I am talking to myself. For me it is hard to practice when the other person is my voice.
The other interesting side effect of knowing the lines cold is when the reader skipped ahead a full page, I didnt miss a beat. I knew it was wrong, but after working with rehearsal 2 the day before , it flowed perfectly. The CD didnt even catch it.
During class, my instructor thanked me for being so much better prepared. I spent about half the time and felt like I had spent all week rehearsing, a luxury we dont get often if ever.
If you dont have a read partner for rehearsal, this is about as good as it gets.
