It may sound like a stalkers dream come true, but dating app Happn is adding a new'creepy' feature that will let potential love matches revisit your past movements. Starting next month, if you remember crossing paths with someone that took your fancy, you will be able to retrace your steps to try and find them again. If they are also a user of the popular dating app, which matches people through their device's geolocation, their profile will appear on the new map tool at that spot. Budding romantics may find the feature appealing, giving them the chance to tap locations they've visited over the past week to track down lost connections. However, some may find the idea of strangers tracing their movements more than a little creepy.

Lonely hearts out there, rejoice--soon Tinder, Bumble, Hinge, OkCupid, and The League won't be your only options for frittering awaytime in your search for love. At its annual developer conference on Tuesday, Facebook revealed that the social media giant is entering the already crowded field of dating apps. "This is going to be for building real, long-term relationships -- not just for hookups," CEO Mark Zuckerberg joked, seemingly side-eyeing everyone's favorite time-suck, Tinder. While "Dating for Facebook" will be opt-in only, the rollout of a plan for a dating app amid the company's huge privacy scandal managed to raise some eyebrows. In an apparent effort to ward off criticism, Zuckerberg immediately addressed concerns that might arise around melding the app you use to see photos of your third cousin's new baby with your dating profile.

Being an online dater might bring a wealth of possible matches to your fingertips, but attracting those matches isn't all that simple. That's why carefully crafting your profile is of the utmost importance. But with no real rulebook for creating the perfect dating profile, it's hard to know what photos to choose and how much info to include in your profile. One chap, however, seems to have got his profile just right, as he's been named the most popular man on Happn in London. He's given us the low-down on how he perfected his profile -- and it's surprisingly straightforward.
