The algorithm ranks Hinge members by their preferences, pairing each member off with the member they would theoretically prefer most. The ‘Most Compatible’ recommendations appear simultaneously for both parties and disappear after 24 hours. To make these pairings, the app learns a user’s preferences through their liking and passing activity and uses that to pair them with a match whose preferences best align.
The method utilizes the Gale-Shapley algorithm, which was developed 56 years ago to solve ‘the stable marriage problem.’ The algorithm traditionally has individuals rank potential partners by level of preference and cycle through proposals and rejections until each individual is with the partner they prefer most (who isn’t already engaged). In the Hinge app, the algorithm is used to avoid endless browsing and increase success. And it seems to work: the new feature is 8x more likely to result in dates and the company saw a 400% increase in user activity after eliminating the standard ‘swipe’ feature.
Why It’s Hot: Although some users are nervous that their discovery will be limited, this introduction of most compatible matches will only make the process more seamless for users and could possibly become the new standard for dating apps and replace the classic swipe method.
