About Jumbo Calculator

Jumbo Calculator is the super simple large-buttoned calculator for everyone. While you can't feel the exquisite texture of its large plastic buttons (and the included solar panel doesn't actually charge your battery), Jumbo Calculator succeeds at its main purposes: adding, subtracting, multiplying, and dividing.

Features:
· Easy to read and find buttons (you might be able to touch type on a touchscreen).
· Simple gestures for backspace (swipe the calculator screen) and copy & paste (double tap).
· A smaller version of the calculator in landscape for when you're too tired to stretch your fingers.
· VoiceOver support for blind and low-vision users.

· Extra precision when calculating with fractional numbers
· Updated graphics for iPad with Retina Display
· Thousands separators (commas)
· Backspace by swiping the calculator display
