7. Tinder
Tinder is one of the most popular dating apps and one of the free dating apps for young adults which uses a very simple technique for matching. You scroll down pictures of singles who live near you and when you see someone you like you can just swipe right. If the person does the same with your picture, then you can message each other and start a conversation. However, if you don’t like what you see then swipe left and that’s it. It does not get any easier than that, right? This explains why so many people like this app. Upgrading to Tinder Plus, though, will cost you a little.
