One day, as I swiped my way through Tinder, a pithy line on someone’s profile gave me pause: “If I was looking for a relationship, I would be on OkCupid.” Every dating app has its own reputation: eHarmony for the older generation, Raya for celebrities, Bumble for women wanting to make the first move. For Tinder, now nearing release in 200 countries worldwide, “hookup app” persists as the unshakable reputation. But Jessica Carbino would like to add a bit of nuance to that perception.
