Simply photoshop
As a free app you cant do much... very basic functionality without paying... but it seems to be a very solid app (as expected). I will still stick to FOTOR because it offers way more functions for free!
EDITED (reply to developer-response): I would be looking for a wide variety of picture-frames, text-adding options, many filters, forms, collage-templates, blurring of parts of the picture, and so on ... all for free (as in my mentioned favorite app)!
