CalcTape Calculator with Tape [Pro]

CalcTape is a revolutionary pocket calculator that keeps your calculations organized and easy to review. Input a long list of values and never lose the overview — just like an adding machine with a paper tape. Whether you work in accounting, manage a budget, or handle everyday math, CalcTape gives you clarity and control over every number.

Fix Mistakes Instantly With Double-Tap

Made a mistake? No problem. You mark the wrong number by double-tapping it and correct it instantly. Every result adjusts automatically, so you don’t have to re-enter your entire calculation. That simple fix saves you time and frustration.

Perform Percent Calculations Effortlessly

You handle percent calculations for tax, VAT, and discounts without complicated steps. The calculator understands percentages and applies them cleanly to your figures. Whether you’re calculating a sale price or figuring out a tax amount, CalcTape does the math for you.

Copy Results and Use Them Anywhere

You copy the current result with a single tap and paste it into other apps. Whether you need to email a figure, add it to a spreadsheet, or share it in a message, CalcTape makes transferring numbers simple.

Edit and See Results Update Automatically

If you change individual mathematical expressions later, the complete calculation updates automatically. You don’t have to start over or re-enter previous numbers. CalcTape handles the adjustments and gives you fresh results in seconds.

Add Comments and Notes Where You Need Them

You input comments on single items and results, and you add notes wherever you want. Every calculation becomes a living document that you can understand weeks later. Annotations turn plain numbers into meaningful records.

Use Intermediate Results to Check Your Work

You use intermediate results to structure and verify your calculations. Review each step as you go, and confirm that every number makes sense before moving on. That transparency makes CalcTape valuable for accounting, bookkeeping, and currency conversion.
