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

The most intuitive calculator app
I can’t tell you how stoked I was to see this app come back from the dead! (It had last been updated yeaaars ago.)
The thing that I like best about this app is that it makes setting calculator memories easy. Honestly who can understand what "M+", "M-" and all that mean on a regular calculator? (Not me.) Here, though, you just drag calculated numbers to a shelf, and you can easily drag them back to the calculation line if you need to use them again.
Best Calculator App, EVER.
Update: I’m still tapping the wrong function buttons. The non-standard layout causes confusion when regularly using other calculators and then this one.
Previous Review: I've been using this app for years and sent several emails to the Dev to ask (then beg) for a 64-bit version.
Here it is: the 64-bit version you've been waiting for!
UI is clean and logically laid out. Functions beautifully and now includes the percent function. The minor rearrangement of the operation buttons makes me tap the wrong one, but it’s a minor eye roll. I am so happy!
Welcome back, Sumhold!
The features we always wanted
Light, smart, and just everything missing on other calculator apps you will find it on this app. Great job!
