A couple of months back a friend of mine suggested me an application named "Are You Interested". The application is a cool one. The app allows you to browse the profiles of the girls or guys which are in their database. You can see their profile pictures and some basic information and if you feel that you are interested in that girl 0r guy then you can click on "Yes" button, You can send them some gifts or message for some credit counts. The user gets notified if someone clicks on his profile or send him something.
This seems to be cool and free. But the developers...
