OP - I assume you are on tinder to get laid, because it's not great for much else. If so, here is how to succeed:
1. drop your standards, swipe on nearly every girl, and see what hits. You can always reject them after you match. there are plenty of girls out there on any given night who might want to have some rebound sex or want to make some guy jealous, or are just really horny. assuming you are not hideous or really really creepy/weird, you can do it. as everyone says, it's a numbers game.
2. work on your profile just a bit. i haven't been on tinder in a while (back then it was just a photo, no profile other than age) but make sure your photos are attractive to women. run them by some female friends you trust, or take some selfies in nice lighting. If you have a typical letsrunners body (and plenty of women like the lean/skinny look, i promise) show your body. Maybe don't flex, but something casual like with friend on the beach or getting back from a run while shirtless. If there is a profile now just make it slightly funny and cool. don't go over the top, and don't make it dorky.
if you are hopelessly hideous or socially inept, i'm sorry. it will be harder. But you can improve your social skills and maximize your assets (ie if you'rea fit runner with an ugly face you can still get girls)
