Aviary (Eye Candy)
Facebook made headlines when it recently bought Instagram for $1 billion, but plenty of other apps can quickly transform your uninspiring photos into artistic masterpieces.
Take Aviary, for example. Its Facebook app gives users access to editing tools, photo effects, and stickers from within their Facebook accounts. Users can edit photos from existing albums or upload new photos, and the app automatically saves the updated images in an "Aviary" album.
In its latest update, Aviary added a custom crop tool that lets you perfectly cut out your Facebook Timeline cover photo.
