Jumbo Calculator is the super simple large-buttoned calculator for everyone, ages 2-92*. 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. One size fits all.

· 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.

If you're under the age of 2, parental supervision is recommended. If you're over the age of 92, congratulations, and of course you're also welcome to use Jumbo Calculator.

Jumbo Calculator

Great calculator until the app doubled in size on my IPad pro, now unusable. How about a fix?

Ads at the bottom get in the way

I was doing some calculations and suddenly the browser popped up. That's because the ads are right under the zero, plus and equals keys. If you must do ads, put them at the top out of the way. Now looking at alternatives.

Nice app but

Doesn't do simple chain calculations like 100 X 8% += should be 108.
