Nova Calc: History Calculator

Change a number. Keep your work.

Adding up expenses, checking a bill, or trying a different amount? Nova Calc lets you edit your calculation and see the updated result without typing everything again.

EDIT WITHOUT STARTING OVER
Tap a number or operator to change it. Correct an entry or try a different value while keeping the rest of your calculation.

KEEP RESULTS YOU CAN USE AGAIN
Completed calculations are saved with a date and time. Add a note so you remember what a total was for, then bring that result into your next calculation.

SEE THE WHOLE CALCULATION
Long expressions wrap across multiple lines. Scroll through your history and current calculation in one continuous view on iPhone.

MORE ROOM WHEN YOU NEED IT
On iPhone, scrolling through your calculations automatically hides the keypad. Tap the floating keyboard button to bring it back and keep calculating.

COPY WHAT YOU NEED
Copy a result, an expression, or a complete calculation to use in a message, note, or document.

EVERYDAY MATH, WITH LESS REPETITION
Work with percentages, decimals, and parentheses. Continue from a previous result, revisit a saved calculation, or change an amount to compare totals.

Useful for shopping totals, household expenses, bills, and all the calculations you may want to check again.
