With CalcTape, even extensive calculations stay clear on your Mac. The software makes the arithmetic visible – you create interim results and correct any number or operation afterwards.

## Features

- Enter many calculation items in one go – and keep the overview, like an adding machine with a paper tape.
- Change any item afterwards – the whole calculation refreshes automatically.
- Use interim results to check and structure your calculation.
- Comment your items to give them sense and context.
- Define your own buttons with your own functions – for recurring tax rates, for example.
- Save calculations as files, reopen them later and keep editing – with automatic recalculation.
- Use existing CalcTape files as templates for similar calculations and scenarios.
- Sync via iCloud with iPhone and iPad, share by e-mail or AirDrop, and print.

- Named values instead of anonymous numbers – variables, brackets and functions keep longer formulas readable. – https://www.calctape.com/img/shots/en/mac-variables.webp
- Several calculations open at once – every document in a window of its own. – https://www.calctape.com/img/shots/en/mac-windows.webp
