Tinder 3.0 Adds Friendship to the Mix

Think Tinder is only about hooking up? Not so much. The app is now venturing outside of being a dating app and into the friend zone.

The latest version of Tinder (on the iPhone) keeps the same basic functionality of choosing each potential date based on a photo and a few bits of information gleaned from Facebook. But this time, you aren't just rating a date, but a potential friend - also with one swipe. Once you and your platonic interest have selected each other as friends, you can add each other to your "friend" list and be able to chat via Tinder. (I'm guessing you can swap notes on people you are hooking up with.)

The list feature in the latest version of the app allows users to customize according to how they want to categorize the people they've approved/ met over Tinder. Maybe according to city where they live, hair color, or height? If you are spending a lot of time meeting people on Tinder, it's a good way to keep everyone straight.

Another addition to 3.0 is the ability to add up to six profile photos, so you don't have to rely on just one to prove how hot you might be. (All photos are visible at the same time, so you don't have to worry about which one potential matches will see first.) Tinder has also improved its algorithms so that you end up with more accurate potential matches.

Founder Sean Rad told website TechCrunch that "eventually, Tinder will create automatic, dynamic lists for users, based on its relevancy algorithm and user preferences, location and interests." In other words, Tinder will notice where you are and who you are interested in (and for what purpose - dating, friendship, work, etc.) and become smarter about sending you matches based on your past swiping preferences.

But the ability to distinguish your Tinder contacts into categories that suit your life - dating, work, or friendship - is a huge breakthrough according to Rad.

"You have certain co-workers, acquaintances, and whatnot, and it would be socially awkward if you added them on Facebook," Rad says in TechCrunch. For instance, if you were to come across a co-worker or colleague on Tinder, you could swipe right and be added to each other's business contact or friends list. It replaces the Facebook dilemna of whether or not to add someone when there isn't much of a personal connection - and perhaps there are some things you post that you don't want them to see. "That's the breakthrough with Tinder," he adds. "That signal has been gone until now."
