Did you ever sit in a restaraunt waiting for your check, while your server walks by, pretending that you don't exist? Now there's a solution.
TipClock is more than a tip calculator. It's a way of communicating to your server: "Hey, you'd better get here soon because your tip is disappearing!"
TipClock displays the current tip in large digits, and gradually decreases it so your server can see his tip ticking away the longer he delays.
