How Tinder changed the dating game

It’s 10 years since the dating app Tinder was set up. It sparked a revolution in online romance by offering singletons a swipe function and the possibility of viewing the profiles of potential soulmates based nearby. The app has now been downloaded by tens of millions of users worldwide.
