The dating app equivalent of playing Russian roulette, CrazyBlindDate by OKcupid requires no personal information what so ever. The only thing you need to do is pick a place and a time and the app matches you up with someone close by who is interested and available at the same time. The name says it all because you’re really taking a gamble here since you have no prior information about this person, which seems to me, would end in disappointment more often than not. The app is designed to save time by not having to put in a lot of effort, but your time will eventually be wasted by going out on a bunch of dates that will most likely end up being a waste of time.
