I have been using this app for over a year. The text is clear even on a small iPhone 5 screen, though better on the iPad. The screens present half of a standard tikun column in the most common Torah layout. Portrait mode shows only the Torah or annotated image, while landscape gives you both, fine on the iPad though too small to use on the iPhone. The app shows the "shvah nah" and "kamatz kattan". My only gripe is that switching between Torah text and annotated text in portrait mode takes 2 taps in exactly the right place-1 to show the menu, the second to switch images. I wish there were a single tap, as the app has for bookmarks. With that said, I use this all the time.
