I don't know the name of the app but I'm looking for the app that enables you to write messages/quotes over the photo, I do a lot of motivational messages with my gym transformation photos. Is there one yet on Z10?
Not sure if you are looking for a free one but for $0.99 there are bunch of them, just a quick browse through App World / Applications / Photography category, first one caught my eye: Photojam. Then there is Text On! for free, there is also one to create Magazine covers. Good luck.
