Thanks for the code - just left a review. This is a feature rich app. One comment is that I think you could make your help section a link off your main page or make it more accessible/obvious somehow. I didn't even notice it for a while, and it sure would have helped explain all the capabilities. A quick popup with what the button does could work as well. Also - a question - I don't see the tags getting exported into iPhoto when I sync. Are they dropped on syncing with the camera roll (or am I not doing it right)? This app has pretty solid set of features for a single package if you are looking for something more capable than the standard camera app.
Good to know you liked the app We shall certainly consider your suggestions. Regarding the tags, all the Meta Data information is lost when you sync the photos to your Camera Roll, as the iPhone OS does not support export of EXIF tags from other apps.
