Tinder added an extra option for its users to "Super Like" another user's profile, allowing users to express open interest towards one another.

The feature was initially tested for the past three weeks in Australia, where women used more than a million Super Likes. However, starting Thursday, the feature was made available to users all around the globe, according to The Next Web.

CEO Sean Rad said that the Super Like proved to have a positive effect on user interactions, citing a 70 percent longer discussion length and a three times greater match rate when compared to those who don't use the feature.

"So much of the things we have in the ecosystem are centered around the idea that men are initiators," he explained.. "What we didn't anticipate is that this has become a tool where women can initiate in a lighthearted way." 

Before the Super Like was introduced, there were only two ways of interacting with another user's profile: swipe right if you like them, or left if you don't. The new feature provides users with the once-a-day option to swipe up.

Rad explained that the limit is intentional. With one Super Like per day (or five if you're a Tinder Plus user), users are inclined to be more judicious and make meaningful matches, according to CNN.

To ensure the Super Like isn't wasted, users who dole out the like will be moved to the top of the recipient's potential matches.

While a neat feature, which has been successful if going by Tinder's testimony, psychology researchers Eileen Chu and Stefano Verrelli following an analysis warned that the feature might make users appear too eager.

"While Tinder's Super Like was designed to help users avoid beating around the bush, according to the science, it may actually be better to hold back and appear more aloof," they said, CNN reported.
