I wanted to make a lie detector app to promote my new book (The Truth App) but my programming skills weren’t good enough. It was easy to make a prank version, though! Open your Twitter or Facebook app, tap the image to make it full screen on your phone, then swipe left and right to “detect lies.”
Tips: Always say “swipe left to reveal” no matter which way you’re swiping. Practice first, to make it convincing!
