Couple (app)

Couple, formerly Pair, is a mobile app which provides a mobile messaging service for two people, especially romantic couples. Like many mobile phone messaging applications, Couple allows users to share text, photos, video and other content. It's a competitor to apps like WhatsApp, Facebook Messenger, and KakaoTalk, but it's unique in that it is for communicating with exactly one other person. Couple is one of a slew of mobile applications that intentionally confine their communication to a small group, as opposed to large public or semi-public networks like Twitter.
