The app works as intended, but it would be greatly improved if it were possible to fine-tune what metadata are displayed. Currently, the choices are "basic", "all", and "raw". The basic info already shows way more than I would like to see. On iOS 5 only, the menu stops working when viewing a photo in full screen mode. The only way to stop this is to force close the app. I look forward to bug fixes and improvements, as this is the only app that truly integrates photos and metadata with maps.
