Quick Sigma

Calculating each item separately, every time you tally? If only you had a calculator for each one. Try swapping your calculator for Quick Sigma.

Enter numbers, calculator-style.

Punching the same items into a calculator, day after day — shop sales, household expenses, daily records. Quick Sigma was built to support exactly that kind of work.

Tap keys like a calculator, and subtotals and totals come together automatically. Each entry is saved as you go — one slip never means starting over from scratch.
