Tired of adding numbers twice just to be sure you are correct? Problem solved.

Adding Tape is an adding machine with a virtual "tape."

Note: Adding Tape is modeled after an adding machine, not a calculator. The behavior of each is different.

Proud to be featured: "What's Hot"

Add, subtract, multiply and divide numbers up to five decimal places, keeps a running total and a virtual "tape."

- Virtual tape visible & scrollable while adding
- Touch/Hold number entry display area to copy/paste
- Edit mode allows you to delete individual rows
- Touch an number in your tape to copy directly to number display area
- Export tape as text or C.S.V. File (Comma Separated Value)
- Save multiple tapes
- Undo an unlimited number of times

* Customize *
- Optional decimal behavior: stays in fixed location as you enter numbers or traditional hit decimal key
- Alternate large Zero key or small '0' and '00' keys
- Option: add line numbers to tape
- Option: set number of Clear Entry touches before tape is cleared

Very clean interface. Gives u different choices for visual look of keys. Good instructions added in the info section. I need a calculator with a tape function and this fits the bill. Developer updated app which is another reason I picked this. Apple keeps updating its system so many developers let their Apps lapse. Pleading keep this app current!!! Thanks. Highly recommend

Very Useful!

Just what I've been needing to include with my other calculator purchases. This clearly keeps a nice record of any calculation sequence which can then be named and saved for future reference. In addition the author updates the App frequently rather than abandoning it like so many other developers.

Have been looking for something like this

Great little calculator for simple math and being able to check your input numbers. Like being able to save and send calculations tape. Number pad plenty big on a Xs.
