I’ve mentioned Pictures Lab a few times here because it’s the app I use for photo editing and mods. It’s great, does anything you’d want it to do (and some), is simple to use and it’s been out for a year. So it has a short term price drop to $.99. If you don’t own it, now is the time. Great app and it will will be with you longer than anything on the dollar menu.
You can check it out here.
