I love this app, a lot of cool features, not heavy on MB at all, basically most of the functions are free, simple and funny to use, the only thing I think its penalty is that if I have an HD picture,or one of a big size, use a filter or any other tool, once I save it to my camera roll or share it, my photo is not HD anymore and much much smaller... Please do something to fix this! let us keep the original size of our pics!
