Hinge also encourages snap judgements, but it tries to offer better matches in the first place.
Though both require a Facebook login, Hinge is more selective in who it presents, only giving you friends of friends.
Happn links users who have crossed paths over the course of a day, taking some of the guesswork out of the equation — if you see a cute girl at a coffeeshop, you can open your app and see if she has Happn too. For a more alternative date, try The Ice Cream Bara picturesque Cole Valley soda shop with swoon-worthy art deco decor.
Whether you live there and you are hoping to expand your horizons, plan to visit and want to know which apps to try while you're in the city, or you're just wanderlusting and thinking about a potential move there someday, here are 10 apps all single San Franciscans should try.
(Both Coffee Meets Bagel and Hinge, above, could fall into this category, too.) If you think most apps are focused too much on looks, consider Loveflutter, which shows you a tweet-length fact about a person before showing you his or her face, or Willow, which begins with a conversation starter.
Score has a similar philosophy, but is set up more like a digital version of "The Dating Game" to get things going by giving you kooky questions to answer.
It also offers a high level of search customization; the Mutual Match function, for example, allows you to find people who are looking for someone like you.
