"Remainder" has been created by two anti-Brexit voters who say they "wanted to cheer everyone up after a dismal day" after the EU referendum on June 23 when 52 per cent of votes were cast in favour of leaving the economic bloc.
"What better way to recover than hooking up with someone who shares your sense of existential dread," its website said.
Remainder bills itself as the "dating and social app for the 48 per cent" and an exclusive platform for those who want to meet new people but also want to make sure they do not unwittingly end up on the date from hell with someone who voted to Leave.
"We created it because all the Remain voters we know seemed so depressed. Our Facebook feeds had turned into a never-ending funeral service. We thought the best way of recovering must be to go out for a few drinks with someone who's in the same boat," the Remainder team was quoted as saying by the Evening Standard.
"We've hit on the perfect indicator of kindness, intelligence and good looks: voting Remain in the EU Referendum," the app's slogan reads.
