Tinder! The app that gives single people some hope, one right swipe at a time. Some have argued that the app isn't that great, while others complain that there are slim pickings out there. Whatever be the case, Tinder has taken the world by storm and revolutionised the dating cum 'hookup' world.

During the testing phase, it was revealed that users with the Smart Photo feature saw an increase of 12% in their matches. Tinder's blog says, "Think of us as your own personal data research team. Which side is my good side? Does posing with the pooch up my game? With Tinder’s Smart Photos, now you’ll know."
