Jumbo Calculator is the super simple large-buttoned calculator for everyone, ages 2-92*. While sadly 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. One size fits all.
· Easy to read and find buttons (you might be able to touch type on a touchscreen).
· Retina graphics for iPad with Retina Display.
· 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 just too tired to stretch your fingers.
· VoiceOver support for blind and low-vision users.
If you're under the age of 2, parental supervision is recommended. If you're over the age of 92, of course you're welcome to use Jumbo Calculator.
