App Description
Based on the experiment by Joshua Brown as featured on the popular science documentary "Through the Wormhole".
On each trial, an arrow appears on the screen, and you must tap on the direction the arrow points to. Each trial lasts only one second. Sometimes, however, an opposing arrow appears, and that arrow's direction must be tapped instead.
How many can you tap?
