Easy photo catagorizing

Hi there,
What is your recommend app for quick basic photo editing combined with adding keywords to photos ( both iPhone & iPad)? I would like to quickly edit and importantly: ad keywords to my photos on my iPhone and iPad, so when the photos through iCloud are downloaded/updated to my Mac and catched by Aperture they are automatic presented in pre-defined Aperture sub folders as: "family", "friends", "town picts", "artistic", "work" etc. ?
