Studies have shown that strong friendships help men live longer. Having a few buddies around also lessens the awkwardness of a blind date. Grouper lets two sets of people mingle casually. Find two friends, select a few dates that month that work for all of you, and the app matches your set with a potential group of the opposite sex. There are no profiles, no photos, nothing. The day before the agreed-upon meeting, Grouper sends you a text with the location and time of your triple blind date. Is it a bit weird? Sure. Could things get really awkward? Definitely. But at least you won't be alone.
