A Calculator on Your Wrist
A watch with a calculator is not a new idea. You probably remember those old Casio calculator watches that sort of lacked in style but made up for it in practicality. But the feature has long been missing from the Apple Watch platform.
While third-party alternatives existed, Apple has finally added a native Calculator app to watchOS 6. That will allow you to do calculations on the fly. Better yet, the watchOS Calculator has a “Tip” button that will quickly let you know how much you should tip at restaurants.
