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.
As a result there is now no end of apps with the same aim of helping you fall in love and live happily ever after, or at the least find someone to hang out with next weekend.
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.
Who wants to date somebody who like Chihuahuas after all?
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.
Verdict: The app that started it all, Grindr has been helping men who like men improve their sex lives since 2009. The USP: Members are vetted, and they also run IRL singles events.
It's disheartening how many women have to resort to 'please no sex pests' appendixs on their profile information.
