summz for iPad


A simple, elegant calculator for performing basic everyday calculations on the iPad. If you don't need the features of a scientific calculator or a record of entries, this is the app for you.


Sometimes, less is more!



new in version 1.1


With the latest release of summz, the operation of the red clear button is now smart!. Once you start entering a number the button operation switches to clear entry (CE). Press to clear the whole number you have entered. When you finish your calculation by pressing the equals button (=) the operation switches to clear (C). Press this to clear all numers and operations pressed. You can of course still clear the last digit pressed when entering a number by swiping left on the number display.


small footprint


summz is designed to be small, so it downloads fast, takes very little space on your iPad and cosumes very little memory when running.
