A unique online dating site intended for men and women who already have one thing in common -- a love of Apple products -- has expanded to provide its own iOS app for its users. Cleverly called Cupidtino, the site (which launched over the summer) allows Mac and other Apple users to browse profiles of other users and send messages, pictures and other info to each other. The company, which is not affiliated with Apple, allows users to start browsing profiles without charge immediately.
