About this app

What happens if you combine a standard calculator App, a classic desktop calculator and a note App ?

CalcTape brings you the best of these and even more.
It is your companion for all daily calculation needs and easily masters all scenarios you can imagine.
CalcTape is NOT a scientific calculator, but do we need these in daily use ?

Ever did a long calculation with many figures and asked yourself:
"Did I enter the last figure correctly ?"
"The result looks strange somehow !"
With CalcTape you keep an overview, can check all figures and correct figures instantly inplace with
all subsequent results being adjusted automatically ! Missed a figure ? No problem: Just insert
it in the right place easily by entering a new line.

You can place the cursor everywhere you like in the calculation: It's like a note where
you can change anything you like in any place with the advantage, that changing numbers
or operators updates your calculation immediately!

CalcTape can be considered a "spreadsheet with a calculator interface".

You can also keep the calculation for your records (documents) and create templates:
Replacing the figures in your template and getting the correct results is a breeze.
Commenting figures and results gives sense to your calculations, so you can understand
what you did when viewing the calculation a month later.
Customize CalcTape to your needs and place only those buttons on your keypad that you really
need everyday. Create your own functions to e.g. add a specific percent rate with a tap on
a single button.

CalcTape comes as a basic free version and offers a Pro update.
The Pro version brings:
- Save your calculations into files
- Create own functions or text snippets to be entered when pressing a button (long press a button to enter the Button screen)
- Create own keypad layouts (change assignment of all buttons except numbers and backspace / change button sizes)
- Select between different keypad layouts (the "function keypad" contains no numbers and is nearly completely customizable)
to get more buttons or other functions, 2 keypads are directly accessible in the main screen
- Share your calculations using standard Android sharing capabilities, e.g. email
- NEW: Print your calculations
- NEW: Export as HTML (via clipboard or e-mail)

I use it frequently and love it. I especially like the ability to go back and edit a calc and it automatically returns the update result on the tape. Easy to save calc runs, and even allows you to place in line text so that you can remember what each section was when you ran it. Awesome tool, exactly what I was looking for

I've been using this app for years, should have reviewed it much sooner than this. I have various lists I keep that occasionally need to be recalculated. The ability to add text to each figure is priceless. I have over 20 calculators on my phone for various special tasks. This is one of my favorites, one I can't imagine living without. Developer has created a Windows version as well.

This app has been really good for years, but a couple months ago it started having a problem: whenever I delete a value in the list of equations, CalcTape suddenly scrolls all the way up to the top of the tape. I have to scroll down through the sometimes very long tape and find the spot where I'd just deleted the value or find the changed result of an equation. It's very disconcerting and slows down my math considerably!
