About eight months later, the two Brigham Young University students wed in the temple of The Church of Jesus Christ of Latter-day Saints in the bride's hometown of Gilbert, Ariz.
And they are not alone. At BYU, the location-based app is a modern matchmaker, helping many to meet and later wed.
Some celebrate nuptials before receiving diplomas from the school, where one in four students is married.
The company's wholesome identity on the Provo campus is a stark contrast from its reputation at other colleges and in other cities, where it is known as a conduit for more casual encounters.
It allows users to narrow preferences based on proximity, age and gender, then thumb through profiles with photos and brief descriptions.

"The hardest part of talking to somebody is that fear," George said. "And now you've eliminated that."
The service caters to a plugged-in crowd, not confined to college students. Its effect on young Wall Street workers, for example, is profiled in a September Vanity Fair article titled "Tinder and the Dawn of the Dating Apocalypse."

Tinder helped him meet more mature candidates, but it wasn't until after graduating that he came across a picture of his future wife.
The two agreed to meet for hot cocoa at Fashion Place Mall.
"My sister was going to meet me to come finish shopping," Graham said, "and I ignored her calls a couple times."
