Polynumial | iPhone App | Translate Numbers to Spelled Words

User's Guide


The app has two ways to enter numbers: keypad mode and counter mode.

Use keypad mode to enter numbers by typing them on a keypad, like you would on a calculator. This mode supports negative numbers and decimals.

The Orientation setting for keypad mode selects left-handed or right-handed keypad layouts.


In counter mode you enter numbers by shifting the digits up and down in each place. Swipe left on all the digits to shift the entire number left (multiply by 10) or swipe right to shift the number right (divide by 10).

In keypad and counter modes tap the spelled number or the localized formatted number to copy it to the clipboard.

Shaking the iPhone to reset the number to zero in both keypad and counter modes.
