MARIECLAIRE.CO.UK - Aug 12 - Tinder, a simple-to-use dating app, launched in the US in September, is now taking the UK by storm. It's a kind of modern day 'Hot or Not'. It's quick, easy to use on the run and the embarrassment factor’s limited. Unlike other dating sites, age is the only vital stat you get. Tinder say they have made ~100M matches since the launch and claim there have been 50 marriage proposals.
