Description from the developer

Professor Brain was experimenting to create waves that increase the brain power, but his experiments went horribly wrong (as always) and made every person DUMB. Now they don't even know what to do in their daily lives. So he quickly makes an app where people can post their questions and get replies from YOU. Don't look surprised there is an app for literally anything these days.
