Calculate — Scientific Calculator

By Joe Rickerby

Open iTunes to buy and download apps.


Calculate is a fully-featured scientific calculator packed with innovative features and carefully designed interface which belies its power.

Unlike other products on the app store, with Calculate, calculations can be entered in the order that they would be written on paper. The symbolic feature reduces complicated numbers to more simple fractions, integer square roots, and more. Previous calculations can be accessed using a familiar swipe gesture.


◆ Fully-featured scientific calculator, including complex numbers
◆ Simple, elegant user interface
◆ Full complement of mathematical functions: trigonometry, logarithms, powers, parentheses etc.
◆ Symbolic mode displays numbers with simple fractional representations as such e.g. ⅝ √2 2π
◆ Calculation history accessed using a swipe downwards gesture on the display
◆ Informative error system makes it easy to correct typos
◆ Four different number display modes: normal, scientific form, fixed decimal places, and engineer mode (using a SI prefix such as k for 1000)
◆ Degree or radian modes
◆ Calculation history saved so you can start where you left off

Perfect for scientists, engineers, mathematicians and students!
