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.

Clearing control

For basic app works very well. One big suggestion needs two clearing buttons. Besides the clear all button, that it currently has; need one to JUST clear an error when putting in a wrong figure to the current balance.

The App Is Good.....

.....But, the ads are annoying.
I wouldn't mind a single ad when it turns on because I understand the need to profit from your work, but the changing ads are really distracting, and I'm sure the developer didn't intend for an app that's distracting
I just restored the old version with no ads because I really like easy access to a basic calculator with big buttons.

I also think when a developer has an update that includes ads where there were none before, they should mention it in the update notes. Saying things like "minor bug fixes" and not mentioning the addition of ads is kind of sneaky.

Very Basic

This app lacks very common features: no memory for partial calculations in a chain. No delete entry, only delete all. Useful for most basic needs. Large buttons makes entry easy.
