How to Get the Most Out of Your Hearing Aids

Cal meets two guys who’ve created an App that does not let you forget anything -- and creates a memory archive. That made Cal feel sharper and healthier in an instant. Not only is the Twos App free. But the founders gave Cal a two-dollar bill as a promotional gesture just to try it out. Cal did, and has been using the Twos App ever since. Founders Parker Klein and Joe Steilberg got so excited to come on Big Questions, they offered to Venmo $2 to anybody who tries the Twos App. Cal’s sure this will delight listeners . . . but he hopes it doesn’t bankrupt Parker and Joe.
