Facebook Gifts can be purchased through the Android app. Birthday or celebration alerts are popping up on news feeds with a link to buy that person a gift. Apple users will be able to buy gifts off the app in the coming weeks.
And better keep you eye on a new iOS app called Photoset. This photo-sharing tool is made by Tumblr, but you don't need a Tumblr account to use it. It allows users to share several photos at once to social networks through one URL.
