Boys online

There's this app called Yellow where you essentially get new Snapchat friends or make out into couples, and I tell you something, they're some really hot guys around my age on there, but I swipe right on them and they don't swipe on me, gutted. Got 2 but one wont reply and another is rude pretty much. I had this app before and I've made friends with a guy I talk to everyday, we both know we're friends and just friends. There's others too but I'm pretty sure we're all mates. Anyone else used this app and have any advice? Cheers
