Tinder and Bumble are two of the most popular dating apps right now. Some users, however, consider these apps to be “hookup” apps rather than dating apps. But where is the dating-hookup line, and does it differ when it comes to gender?

“A group of scientists at the Queen Mary University of London, Sapienza University of Rome and Royal Ottawa Health Care Group studied the behavior of Tinder uses and found that women generally swipe right only for men they’re seriously interested in, while men are less picky,” according to Business Insider.

This makes the app Bumble so popular. Bumble is a dating app where the women are the only ones who can send a message first. This gives women more opportunities to have control when it comes to dating.

On top of this, Bumble gives users the option to upgrade to Bumble Boost, which allows users to see who has already swiped right on them and narrow down the searches.

Tinder has a similar feature called Tinder Gold where users can see who has already swiped on them. It also allows for unlimited back swipes, meaning if you accidentally swipe left, you can backtrack and swipe right.

Another feature to Tinder Gold is the “super like,” meaning it lets the other person know you have a really high interest in them and hope to match.

More recently, women began putting the phrase “no hookups” in their bios. This is because, in the past few years, apps like Tinder and Bumble have become places to find hookups. Tinder became the source of the “Netflix and chill” meme because that is how the hookup approach went.

For those who are looking for friends, Bumble has an option for that. There is a specific setting on Bumble called Bumble BFF and it’s where users can find other users that they would like to become friends with. There is a third setting called Bumble Bizz, and it is a setting where hiring businesses look for potential employees.

We all have probably had a few Tinder or Bumble conversations end in awkwardness and embarrassment. It’s important to keep in mind the different reasons people on dating apps have profiles and what their intentions are.

Only seven percent of male matches sent a message while 21 percent of women sent a message first, according to Business Insider.
