CalcNote is a new generation of calculator designed for the smart phone.
Just type a expression, the answer will be displayed instantly. No need to tap equals.
It works like notepad or your word processor, you can see multiple questions and answers all at once.
It's like a spreadsheet but much easier and simpler.
If you make a mistake, you don't need to start again, you just fix the wrong expression.

Instant calculator & realtime results
CalcNote will instantly evaluate any mathematical expression and display result in real-time.
With a Notepad-style interface you write operations on each line and see results instantly.
You can combine text-lines with calculations.

Multi-line calculations & references
Every line in CalcNote is evaluated so you can write different operations on each.
It even allows referencing lines as in Spreadsheet so you can do multi-line combined calculations (i.e. $2+$3 adds up the results from line 2 and 3).

Different keypads with operations
Swipe right-left to switch between different keypads with multiple operations you can perform.
Regular mathematical operations, logarithmic, trigonometric functions (i.e. sin, cos), permutations/combinations as well as a percentage calculator and unit converter.

Save & Export
In CalcNote you can organize your calculation sheets in folders, save them individually and even export expressions if you want to use them elsewhere (i.e. in Spreadsheet, in a scientific paper, etc.).
