How many times did it happen to you that you found out that you and your friend or someone you barely knew, have the same friend or know the same people for years, but you just never realized it?
Use the Small World Application to SWAPP your mobile phone contact list with the contact list (address book) of your friends and just enjoy the show.
As a result of the exchange, the users of application will not have any new contacts to see or save. Only those contacts that they have previously had but are common to both users will be displayed on their mobile phone.
The final purpose of application is to connect people by giving them an idea how many common friends they have and to show them how this world is a really small place.
