I have this in my iPhone and it works great!! My main use is really to cement the lines in my head once I have done a very cursory memorization. I hook it up to my car stereo so I get 70 minutes of rehearsal every day while going to work and back. I had a weeks notice before a play to learn about 20-30 minutes worth of lines and this helped me very much. I am now using it to help me learn Albany in King Lear. This will only be my 3rd play and I would be lost without this app. I highly recommend it!!
