  • Men only: Across all apps, how many matches/day do you get?
    So basically https://happn.com/, it's to find people around you, that have been in the same places. I'm a bit to shy to just ask a random girl out for a date, at least there, we both know we are looking for something similar. Source: over 3 years ago
  • Is there a dating app…
    Https://happn.com/ the problem is that very few people have these apps. Source: over 3 years ago
  • Using Google Maps history to see if my boyfriend and I could have met earlier
    There's actually a dating app with a similar-ish concept called Happn (https://happn.com/), which basically is Tinder but if Tinder only showed you the profiles of people you had actually crossed paths with in real life. Fun fact! - Source: Hacker News / about 4 years ago
