How about being able to change that operation from +1 to -5 or *7 or / 3 or even ^2 and being able to repeat any of those operations as many times as you need?
Or how about being able to repeatedly take the square root, cubic root, or any other root you can come up with - as many times as you want?
Introducing Quick Tally - a cross between a tally app and a basic calculator with six most commonly used arithmetical operations, along with the memory features which are standard to any calculator.
Featuring four large, customizable buttons, Quick Tally offers the ability to add, subtract, multiply, divide, power, or root numbers repeatedly with fewer key presses than a standard calculating app, saving you time!
Also, thanks to its large buttons, Quick Tally allows you to focus on what you're trying to tally because you don't have to look at your device every time before pressing a button to tally up.
