An app used by thousands of people that offered by answer engine Wolfram that analyses the information people put on Facebook, and shows their account activity in charts and graphs.
Pie charts reveal the ratio of their friends' relationship statuses and maps plot their locations by global city.
If the user has included their date of birth the app will also tell them what the weather was like that day, the BBC reports.
British physicist Stephen Wolfram, who came up with the idea, described the app's functions as 'personal analytics for Facebook'.
According to the report, the app also reveals a user's most popular posts and generates a word cloud in which the most frequently used words are displayed the largest.
Wolfram Alpha works directly from data already online to provide a definitive answer to a question rather than providing links to other websites like a traditional search engine.
