Tinder is a very strange app. For those of you who aren't familiar, with the app you swipe left on people who you aren't interested and right on those you are crushing on. You can set which gender or both if that what you're into,and an age range for example 19-23 years old, and you will only seen people in that range. A person can have 1- 6 photos, and a short bio; that's a slim bases to judge someone on so it's risky. When you both swipe right on each other, you then become a match. After the match is established you can then message each other a funny joke or a witty pick up line.
One of my favorite features is the un-match button. So you match with a cutie, but they sent you something totally weird; you can un-match them right then and they are unable to send you anymore messages.
Nine times out of ten you're going to see someone you know. You can either ignore them or swipe right on them like I do to make sure they know you saw their profile unless it's your brother (personal experience).
Tinder has caught this bad reputation being known for hook up's. However, as I mentioned above the nice un-match feature, as soon as someone brings up anything I am not comfortable with I simply hit un-match, easy.
Truthfully, I have come across many guys who I ended up being not as romantically interested in, but I have made numerous friendships. I have a large number of friends I hang out with often all thanks to Tinder.
It's not all about hook up's or even relationships unless that's what you're looking for. Just like everything else in life, Tinder is what you make it.
