If you lack inhibition, Hinge could throw the door wide open.
This hook up app for friends (and friends of friends) is the equivalent of passing 'I Like You' notes in class.
£5 a week for the advanced user options is just too much, though.
The USP: Like Tinder, except once you match, only the ladies can make the first move and say hello.
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.
Verdict: The more you think about it, the less sense Down makes.
