evalute befor you buy ,

a revision to my previous review

My earler review was critical. I thougt the app would be able to restore old photo. the developer did not claim it was so it is my mistake not to carfully evaluate befor buying. The app offer many very usful features and ease of use. My earlear review is not justified. i give it four stars for the features it offer.

Rock Your World with Posterino 3

I have been looking for a good collage/montage creating app since Picasa died. This is the best I have found, because of the breadth of possibilities for assembling images and also the ease of use, at least for someone like me who has had experience with a variety of photo editing tools. I will have to come back and revise this review because there is so much it can do. For now, though, I am ready to plunge in!
