Tip 'n Split looks like a typical calculator, but it’s streamlined to determine the tip then the amount each diner owes—and that’s it. Connie Inukai created it for retirees like herself.
She and her friends would have difficulty reading menus and the bill while dining out, and many didn’t own a smartphone. So Connie’s device does the dining out math, and it has a built-in magnifier and LED light, too, to help see things in dim lighting.
Using Tip 'n Split is intuitive. On-screen prompts help you divvy up that check with a few taps.
