CalcTape Paper Tape Calculator

Every calculation. In context.

CalcTape combines a calculator, an editable calculation tape and space for notes. Plan a trip, check shopping costs or keep track of expenses with your figures and explanations together.

KEEP EVERY STEP IN VIEW
Enter several items, create subtotals and add comments beside the numbers. Use arithmetic, percentages, powers and other functions while keeping longer calculations easy to follow.

CHANGE A FIGURE, UPDATE THE RESULTS
Edit a number or an operator, insert a line or remove an item. CalcTape recalculates the results below automatically. Undo and Redo let you reverse and restore changes.

SAVE YOUR WORK
Keep calculations as documents, reopen them later and reuse them as templates. The document list shows the storage location, date and line count. Choose whether a document opens at the beginning, at the last position or at the end.

MAKE IT YOUR OWN
Customize keypad layouts and create buttons for frequently used functions or text. Choose from five designs, including Dark Night with a dark calculation sheet, keyboard and dialogs.

SHARE AND CONTINUE
Share calculations as text, HTML or CalcTape files through the iOS share sheet, or print them. Use iCloud Drive to access your documents on other devices.

FOR IPHONE AND IPAD
The calculation sheet and keyboard adapt to the app window. On iPad, work alongside another app.

Version 6.1.0 refreshes the interface and improves document handling, saving, synchronization and calculations.
