(Not Boring) Calculator vs Auth.Jc

"Just astonishingly fun." — John Gruber A BETTER EVERYDAY CALCULATOR As a kid, I loved playing with a calculator. Somewhere along the way, the calculator became another boring tool. I want a calculator that reignites that same sense of wonder. SHOW YOUR WORK One of the biggest obstacles with most calculator apps is just how easy it is to make mistakes. If you mistype a number and don't catch it immediately, you can easily end up with the wrong answer and never know it. To fix this, we do what everyone is taught to do in elementary school… we show your work. As you type, the full equation is written out for you—every number and operator. Even better, if you make a mistake, you can now delete or select the number and retype it. Small, but life-changing. PLAYS LIKE A GAME, WORKS LIKE AN APP Next generation user interface designed and built in 3D with animation and sounds inspired by video games. % Percentages can be a challenge to wrap your head around, so we built it in. BIG & READABLE Big numbers that are easy to read at a glance when you're darting across screens. SKINS Skins change the whole look and feel of the app. New skins and collaborations every season so you can keep it fresh.
