CalcTape for iPhone & iPad is a calculator with an editable paper tape: even extensive calculations stay clear and can be corrected afterwards, with an interface optimised for the touch screen. One universal app for both devices.

## Features

- Enter many calculation items in one go and keep the overview – like an adding machine with a paper tape.
- [Change any item afterwards](https://www.calctape.com/en/manual-ios#modify-calculations) – the whole calculation refreshes automatically.
- Use interim results to check and structure your calculation.
- [Comment your items](https://www.calctape.com/en/manual-ios#adding-notes-and-comments) to give them sense and context.
- [Create your own buttons](https://www.calctape.com/en/manual-ios#custom-buttons) and whole keypads – on iPad also with a long press.
- Sync your calculations via iCloud between iPhone, iPad and Mac.
- [Send calculations](https://www.calctape.com/en/manual-ios#sharing-and-printing) via AirDrop, Messages or e-mail, and print them.
- Undo and redo any change you make.
- [Save calculations as files](https://www.calctape.com/en/manual-ios#saving-a-document) and reopen them later to keep editing.
