Update: the devs listened and added קמץ קטן! As a tikun, it now has everything I need. My one suggestion is that a multifinger gesture to switch between the Torah side and "cheating" side would be nice.
Heck, since this is digital now, why not do some cool, out-of-the-box stuff. How about a tap-and-hold interaction that would reveal a magnifying glass to peek at a specific word. Or maybe a way to turn off the trope and vowel layers separately. Or a way to repaginate/re-lineify/re-columnerize it as a way to test myself in case the actual Sefer Torah happens to be different.
Also, since the iPhone is so much smaller (especially the non-retina 3GS), landscape mode should have a way to not show side-by-side. Again, a two-finger swipe to toggle views would work.
Just some random thoughts. :) But seriously, this is a great app.

Previous review: I just downloaded this, and so far it seems great. I really appreciate that it indicts שוא נע. My only complaint so far is that it doesnt also indicate קמץ קטן. But this will still be great for going over my leyning during my commute!
