As an artist and designer I’m not supposed to be good at, or like Math. While I’m no mathematician I can hold my own and try not to use a calculator for basic math like addition, subtraction, multiplication and division. I actually don’t mind doing math, it keeps your brain sharp, and as I get older I need a sharp brain.
Designer Chad Voss has created a new iPhone calculator app that I really like, and if I have to use a calculator, I think I’ll be choosing this. “Sumhold” not only looks great, it does something that other calculators don’t. It shows you the equation, and visually holds it so you can see what your last function was.
Math done simply. Designed in the Swiss style, Sumhold is a calculator that instantly calculates and stores numbers with a fiercely reductive interface and simple swipe gesture.
Unlike most basic calculators, Sumhold keeps a running tally of your current calculation at the top and, when calculations become complex, automatically inserts parentheses to keep everything clearly readable. There is no need for an “=” button because it calculates as you type.
