Best iPad Photo Apps: Fotolr
A useful app for making quick edits, you can rotate, cut (crop), resize and doodle on images.
Changes to Brightness and Colour can also be made, along with adding text. ColourFX offers a few different filter type effects, and although not as creative as some of the other apps in this list, they’re still worth a look.
One particularly useful feature is the ability to compare the edited photo with the original.
