Singapore's government dating app, First Date, uses the Gale-Shapley stable marriage algorithm, a Nobel Prize-winning method from 1962 that also powers hospital residency matches and kidney exchanges. The algorithm ensures mathematically stable matches where no two people would prefer each other over their assigned partners. Users build ranked preference lists, and proposers offer to their top choice iteratively until stability is reached.
The UX features one match per cycle, a 72-hour decision window, and contact info revealed only on mutual yes. All users are Singpass-verified, ensuring identity authenticity. Currently limited to public servants aged 21-35, the app is designed to get users off the platform quickly, contrasting with commercial apps that rely on endless swiping.
As proposer-optimal, the system favors those making the first move in stable outcomes.
