The first genetics-based dating app, called Pheramor, is expected to launch in 2018. The name is based on pheromones: https://pheramor.com/pheramor-kit/
The founders say: "Genetic-based human attraction has to do with pheromones. And when we smell pheromones, what we're actually smelling is how diverse someone's immune system is compared to our own."
"Evolution is very strong. So we're smelling each other, trying to figure out who is the best person to mate with. And that's what love at first sight actually is. It's smelling someone's pheromones from across the room, and your brain says, "That's the most perfect pheromone profile I've ever smelled in my entire life. I love them."

When someone swabs their cheek with a Pheramor kit, the lab scans for 11 genes, which scientists have linked to attraction.
