The USP: Gives you the chance to tell your friends (rather than strangers) that you want to sleep with them.
Pros: There is a strange thrill in being able to 'swipe' that acquaintance you've always fancied, asking them for a date (up) or telling them you want to sleep with them (down). Cons: It pulls in every single woman who happens to be your friend on Facebook, even if they haven't joined Down yet (your cowardly come on will be waiting for them if they ever do), making it rather pointless.
It's disheartening how many women have to resort to 'please no sex pests' appendixs on their profile information.
Verdict: Easy to navigate, simple and free to use, void of distracting gimmicks. Pros: Easy and efficient to use, you can find a hookup within minutes.
Cons: People might think basing your future parter on dog preferences is weird Verdict: A silly app that seems unlikely to find you true love but might narrow down options.
