That’s relationship, singular–not what you have with your 2,436 friends on Facebook. Oh, you say, to talk with close friends I use the Path app. Then what you may need is Couple, the app that’s exclusive to those who are exclusive. Won’t give you a lasting record of your love, both the quotidian and the sublime, the way the Couple app will. As of today Couple has more than a million users–which is really kind of half-a-million, no?
