So you're Tindering away like usual, deep in a marathon of left-swipes when — bam — it happens: You accidentally swipe left on someone you're pretty sure might be your soul mate. You curse the world for being so unfair and try to get back to your business, but you can't seem to get that photo out of your mind. The one who got away.

Why were you so hasty to swipe left? Why isn't there any way to undo this grave error? The only option now is to stew in your regret. But soon, that will change.

Brace yourself, online daters: Tinder is getting an "undo" button. But the bad news: you'll have to pay for it.

According to a report from TechCrunch, citing the dating app's co-founder Sean Rad, Tinder is moving ahead with plans to roll out a paid version of the app that will bring two premium features: the ability to undo erroneous left-swipes and search for people outside your geographic region.

"The most requested feature we get is a button to go back and have a second chance with people that users swipe left on," Rad told TechCrunch. "Everyone has wanted it from the beginning. It's absolutely at the top of the list."

The other premium feature, dubbed Passport, will let you search for matches in a different area — vacation hookup, anyone? — and toggle between your locations. Right now you can only search for dates within your general location, but with Passport you'll be able to find potential matches all over the world.

Now for some more bad news. At this point, Tinder is still testing these new features, and is only making them available to about 40 percent of its users in select countries, including the U.K., Brazil, and Germany. So that means if you're in the U.S., you're left out of the party, for now.

Tinder is testing several different price points ranging from $0.99 all the way up to $19.99 in some markets, to see how much money users are willing to pay for a second chance at love. The plan is to roll out the feature globally in the future, so just sit tight and Tinder with care in the meantime.

If they're willing to pay by the minute, Tinder might be swimming in cash. The company recently revealed that Tinder users check the app an average of 11 times a day. Women spend as much as 8.5 minutes swiping through matches during a single session, while men spend 7.2 minutes. That's more than Facebook or Instagram.

Also on the social front today, Twitter announced a small change that should make it a little easier to tweet on Twitter.com. You can now compose your tweets from the top of your timeline.
