Singapore built a dating app with a Nobel Prize algorithm

Singapore's GovTech agency built a dating app at its annual hackathon. It's called FirstDate. Access is limited to civil servants aged 21–35. You get one match every 72 hours. No feed, no swiping.

The matching engine is Gale-Shapley — the 1962 algorithm that earned a Nobel in Economics in 2012, and that already runs under Hinge. The core property: it produces pairings where no two people would both prefer each other over their current match. Mathematically stable. Chemistry not included; GovTech says so explicitly.

Logins go through Singpass, Singapore's national digital ID, which filters out married users. The whole thing started with one question the hackathon team kept arguing about: does having more options actually help you pick?

A government running a Nobel-class matching algorithm to solve a fertility crisis is a sentence that shouldn't work. It does.
