WEST HOLLYWOOD (CBS SF) — The popular dating app Tinder, often shrugged off as a hookup facilitator for twentysomethings, launched a premium addition that now charges based on the user’s age.

On Monday, Tinder included two new features in its paid app version: Rewind, allowing users to undo a left swipe which would indicate that they’re not interested, and Passport, allowing users to search for profiles in other geographic regions, in case they’d like to plan a hookup before traveling abroad.

But there’s a catch. Users in the U.S. will pay $9.99 for Tinder Plus if they’re under 30, and $19.99 per month if they’re 30 or older.

A Tinder spokesperson told CBS News that in several months of testing Tinder Plus, the company determined “that these price points were adopted very well by certain age demographics. During our testing we’ve learned, not surprisingly, that younger users are just as excited about Tinder Plus, but are more budget constrained, and need a lower price to pull the trigger.”

She also pointed to Spotify as another company that has a tiered pricing structure based on age, charging less for users with not much disposable income, like students.

Meanwhile users in developing countries can upgrade for as little as $2.99 per month.
