It's not like there's a shortage of sexy, interesting singles out there—you see good-looking people all the time. But how do you approach a stranger in a random, everyday setting without seeming awkward or, worse, creepy? And are they even single? By the time you've worked up the courage to say something they've disappeared into the crowd, the (potential) love of your life gone forever.

And that is the genius of Happn, the dating app that connects up with other singles who go to the same places and enjoy the same things as you do.

Spot someone intriguing at your favorite afternoon coffee shop? Or at that art thing two nights ago? How about that cutie you always see waiting for a train in the morning? When you cross paths with anyone on Happn during the course of your day, they'll show up in your timeline, with a profile, photos, and the location where you passed each other. Now not only do you know that they're interested in meeting people, you also have the perfect ice breaker.

Happn just crossed the 10-million-member milestone, and since both the concept and the actual user experience are pretty unique and great, Happn is well on its way to having 30 million singles by year's end.

Plus, there's a new flirting tool on Happn, a voice feature that allows you to embed recordings of up to a minute into your texts with other members. Don't worry though, like all of your interactions on Happn, you can only receive voice messages from someone you've "liked", so you're not going to start getting deluged with, say, unsolicited love songs. Just solicited ones. ;)

Happn brings a welcome chunk of the real world into the realm of online dating. All you have to do is download the free app, spend a few seconds creating a profile (you can grab photos from your phone, your Facebook, and your Instagram), and then just go about your regular day. Only now, when you see someone you might want to meet, you can connect with them instantly before making your move.

Happn is available on Windows phone, iPhone and Android.
