Tinder added more 1.2 million subscribers in 2018 alone.
Match Group - the parent company for the online dating app - has revealed its fourth quarter earnings this week, and revealed that the surge in memberships meant the brand ended the year with $805 million in revenue.
As reported by The Verge, the Tinder figures are almost as much as the company's other dating services - including Match.com and OkCupid - pulled in together at $872 million.
Match has credited most of the revenue growth to Tinder Gold, which allows users to use features likes Super Likes more frequently, as well as the ability to swipe around the world and find out who's already liked them.
Meanwhile, Tinder itself is looking to focus on the 18 to 22-year-old demographic through its university-oriented section Tinder U.
It will also look to expand outside the Us and focus on markets in India, Japan and South Korea.
Despite the huge growth, Match is looking to go beyond the platform rather than putting too much emphasis on one product.
It has introduced a new app Ship, which is designed for women and to encourage group chats about dates.
It has also fully purchased Hinge after partially doing so last year, and downloads for the service have gone up four times year over year by the end of 2018.
