The ultimate argument settler!
Ever had an argument with a friend over where to eat, or which movie to watch at the cinema? It used to be that the only way to settle the decision was to flip a coin, but who still walks around with coins in their pocket? Rather than flip a coin like your grandfather used to do back in the day, simply tap your friends phone and Shake On It! Tap to begin, then shake your phone like you mean it! When you're done, tap again, and the winner will be decided. It's as simple as a handshake, but way more fun!
