History and Favorites. Instead of having to type out long equations over and over, simply favourite them and retrieve them with a single tap. Guaranteed to speed up your workflow enormously. Material Design. A calculator app doesn't have to be bland and boring. Let the subtle animations and vibrant colors guide you throughout our app. If you've purchased the Productivity Pack, select from a variety of beautiful themes including our battery-saving "Starless Night" theme. Android's most intuitive scientific calculator. Other calculator apps make you enter equations on a single line. They're slow and difficult to read. To fix this problem we've spent the last 8 months designing our Natural Input Engine. We've made it so that you can enter equations as you'd write them on paper, using fractions, roots, exponents and more. It's called a "natural display" and is a common feature on scientific calculators like the fx 82 or TI 30XB, and we've finally brought it over to Android. Fractions, exponents and surds. We've made structures like fractions display naturally as it does on paper. Updates. For the last 8 months our team has worked day and night to implement new features and updates - we're not going to stop anytime soon.
