TInder: The best free dating app lights up Sochi Olympics

You're a world class athlete. You're cold. Tired. It's Valentine's Day. Of course you're a little lonely, and maybe feeling a little frisky. What else do you do but grab your smart phone and swipe through some profiles on Tinder, the best free dating app since Grindr that let's straight people hook up with the swipe of their finger.

Like it or not. Mobile or online dating is catching on and fast. According to recent statistics, one in five relationships in the UK now start on the internet, with over 9 million Brits allegedly registered with a site such as Tinder, Grinder, or the increasingly outdated e-harmony.

Tinder is a free speed dating app on steroids. It lets users browse profiles (usually connected to Facebook), then swipe right to 'like' them, or 'left' to ignore them. Once your profile is liked, you can message each other and blast off into real life conversation, or skip straight to the sheets.

Though some have argued that Tinder represents the lowest of the low among free dating apps, it is what it is: a place for young people to shamelessly hook up, and potentially date. Not much different from a nightclub, minus the outrageous cover charges and possibility of getting roofied. 

And Olympic athletes are no exception. According to the Wall Street Journal, Tinder has seen a 400% day-over-day increase of new users in Sochi since the Olympics opened Friday. It's gotten to the point that 23-year-old snowboarder Jessie Anderson allegedly had to delete the app from her phone.
