After signing up, Happn showed me 68 users it said I had crossed paths with in the preceding three hours, though I hadn't left my apartment all day.
It's a cool concept and helpful for people who want to meet someone in a more organic manner.
That said, I've never met a single person who actually uses the app.
Frankly, if I saw a cute guy in a coffee shop, I'd just approach him rather than check to see if he's on Happn.
The app seems designed for people who don't want to use online dating but who also don't want to approach people in real life. The League is an "elite dating app" that requires you to apply -- and supply your job title, college and Linked In profile.
But if you're someone who procrastinates, Bumble may not be for you.
