Tinder has been the quick-matching app of choice for singles since 2012. It has quickly evolved into an app with 50 million users without adding any new features. Now, the app is going to get more features, but only to members willing to pay for those features, TechCrunch reports.

Tinder Plus is expected to come out in March. The premium service will come with an Undo button for accidental swipes, and a Passport option that will allow users to see matches outside of their location.

In the Google Play and Apple App Store's recent updates for the basic Tinder app, Tinder Plus features were mentioned, hinting that Tinder Plus features are coming soon.

Tinder says that the next update will get rid of these feature mentions and is still targeting a March release for the Tinder Plus app.

In the U.S. App Store, Tech Crunch noticed the following text in the version 4.1.1 (the latest version) Tinder app update:

"Undo - Take back your last swipe! - Passport - Change your location to match with people around the world! - Bug fixes" 

Now, if a user wants to update their Tinder app to 4.1.1 on the App Store the only updates the app says it received is "Bug fixes."

On the Google Play Store, the text about the Undo and Passport features are still displayed.

In other countries Tinder Plus is already available, meaning those who have Android devices in those countries are reading the text about the new features.

Tinder might change the text displayed to U.S. users because it could get awfully confusing to them.

The price of Tinder Plus could depend on the features customers buy through in-app purchases, or it could be one stand alone price.

Only 40 percent of all Tinder users currently have access to Tinder Plus as the company continues to test out the premium app in select markets.

NationalReport suggests through a leak that Tinder Plus will cost $6.99.
