The USP: Endless personality quiz questions that give you a match percentage with would-be partners. The USP: It's a huge ocean, with more members than any of the others (around 70 million).
And unlike Tinder, users tend to write a bit about themselves, meaning you have more to go on (and sell yourself with) than just your 5 least-worst selfies. Cons: It is notoriously 'glitchy', with messages disappearing and some functions not working properly.
The USP: Hook up with the people you walk past on the street.
Pros: Once you get over the slight stalker complex Happn instils on you by showing women who walked past your front door an hour ago, matching with users within a 250 meter radius is actually quite handy.
Verdict: Worth a shot, if only to kill time answering bizarre questions about yourself. Cons: A high number of sexually frustrated virgin-trolls means a lot of women find using it a harrowing experience, which understandably makes them cagey when you come along.
It's disheartening how many women have to resort to 'please no sex pests' appendixs on their profile information.
