What's New

This app has been updated by Apple to use the latest Apple signing certificate.

The long awaited percent button is finally here! And now Sumhold is a 64-bit app so you won't get those pesky warnings any more. Also I've added anonymous telemetry that you can turn off in the settings.

App Description

Math done simply.

Sumhold instantly calculates and stores numbers with a streamlined interface and a simple swipe gesture. Need to remember a number? Just swipe it down to the number pad to save it as a button.

Sumhold also keeps track of long calculations in an easy-to-read line. It shows a running total and eliminates confusing buttons present on other calculators.

Features:
- Swipe to Remember
- Running Total
- Tracks long calculations
- Automatic parentheses for redability
- Copy/Paste Support
