Social Searcher

Social Search allows you to search for Facebook people, post, pages, groups and events

You don't even need to log in your Facebook account. Input a keyword into the search bar, sort search by date/time, by country or by number of likes and you will get the info available for people, posts, pages, groups and events. This is basically what this app does.

Although it's easy to use, the layout could be certainly improved. What's more, we really were wondering the utility of this app: with 800 millions users (and keep growing), you'll probably have a Facebook account. This means that you don't need to use an app for searching without logging in. Anyway, if you want to see people's profile when logged out in order to see how your profile (or others) would look like, then give this a go. Otherwise, you'll probably find it worthless.
