Importing files using iTunes is a bit glitchy (often doesnt work), and there is a major battery drain associated with this app, but other than that, I love it. This makes college much easier. I dont have to use pen and paper anymore, and I can record lectures while taking notes in the same place. When playing back, the notes are dimmed, and become full color as the lecture (audio recording) progresses. To work around the iTunes import issue, Im having to upload all of my files to Dropbox, and them import them to Notability through there. To work around the battery drain, well, I dont know. It lasts through two classes (about 3 - 3.5 hours) and then I need a recharge. Not running anything else, so I have isolated the problem to Notability.
