It's also perfectly suited to mobile use, such as when you're in the pub, you've had a few beers and you've got your game face on. Just download it, log in with your Facebook profile, specify the gender and age range of the people you'd like to meet, and how far you're prepared to travel to meet them.
When Tinder finds people who match those criteria it places cards on your screen that show a large photo of the person; tap this to see a short description they've written.
The people we've spoken to about Tinder like it because it's so simple: there's no 400-question registration process, and it doesn't put you in a box for - as an example - saying you're a non-smoker when actually you have been known to indulge on occasion and wouldn't particularly mind dating someone who smokes.
And while personalities are ultimately what's important in a long-term relationship, Tinder recognises that when developing an attraction establishing how well suited you are to a person often comes second to the way they look.
And I'm not entirely sure why, since I'm not single.
But it just goes to show how interested are people in the dating app.
You decide whether or not you like the look of a person: if you do, great; if you don't, they'll never know.
If you're both interested then Tinder's messaging function offers you a private chat thread in which to talk and get to know each other better.
Normal users can only swipe right on so many users per day before they have to wait 12 hours - a way of discouraging people from trying to match with every profile they come across. Pricing is determined for each user by Tinder's algorithm, with prices based in large part on your age: the younger you are, the cheaper it costs.Previously you would need a Facebook account to log in, but in the wake of the Cambridge Analytica scandal Tinder added the option to create an account using only a phone number.That will prevent you from using some of the app's features though, such as pulling photos directly from Facebook, and showing you when you have mutual friends or Likes with another user.Below the picture is a heart icon and a cross - tap the heart if you like them and the cross if you don't - or swipe to the right if you like them, and to the left if you don't.If you like someone who also likes you Tinder will tell you that a match has been made and opens up a simple messaging function. Tinder pulls some information from your Facebook profile, such as your job and education, but you can choose what to display and write out a short bio of yourself.
