Tinder and Duolingo have teamed up to help singles learn to flirt in new languages. This comes as the dating app has seen a huge increase in people using its ‘Passport’ feature. This feature allows people to match with other users around the world. Tinder is now giving 100,000 users a free month of Duolingo Plus to help them find love internationally. Tinder members can ditch Google Translate and take up free lessons on Duolingo to better communicate with their long-distance connections, Tinder. Tinder says that 76% of Passport users have matched with another user that speaks a different language. The dating app has also made its Passport feature free to all users until April 30.
