Grindr also announced that they're working on an option for users to notify potential partners of their STD status as a way to stop the spread of infections among dating app users (particularly HIV and AIDS). They've tried this sort of thing before, but had some issues with sharing users' health information with third parties. Overall, their hearts are in the right place, and I commend them for trying to promote the importance of safe sex.
Most dating sites will match people on the traditional personality traits and interests — and having the same values and hobbies as your SO is obviously important. But what the creators of other apps might be ignoring is the fact that there's one thing stronger than the bond from two people liking the same thing, and that's two people hating the same thing. As seen on ABC's Shark Tank, the hater app is basically Tinder for people who have very strong feelings about the things they hate. This is perfect if you hate everything your ex loved, and you're trying to ensure that you never date a person like that again. Hate anything from slow walkers, to Donald Trump, cargo shorts, the phrase "Live. Laugh. Love," you name it — you know, all of the important stuff that matters in a relationship.
