About this app

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, save them individually and even export expressions if you want to use them elsewhere (i.e. in Spreadsheet, in a scientific paper, etc.).

I rarely want to take the time to provide a review, but this app is the exception. It is so awesome 😎. I use it to maintain a monthly budget, as well as keep track of checking, etc accounts - especially my credIt cards!!! It is so flexible in being able to use text or numbers or calculations. I wish I could include a pic of what I have creatively designed. It is so easy to quickly enter the amount of money spent, credited, deposited or transferred while on the go! THIS IS MY FAVORITE APP❣️

It has a lot of features, the ability to backup files, and an almost needless ability to personalize thematically. The ads are a little bit of an eye sore, but i haven't found them intrusive, and the app is free for a good quality. So no real complaint. The only thing I might like is a tutorial? But maybe there is one already.

I love CalcNote. I like being able to use the alphabet & numbers, for taking notes on each mathematic step. I'm thankful for it very much. It's simplicity is my favorite part. I also like how you can save it in separate files. Thank you for making such an app! The only thing I'd change is, if possible, making it so it can automatically save in Google drive, rather than the device.

Thank you for using CalcNote and writing a nice review. I provide CalcNotePlugin for Drive as a paid app ($0.99). This plugin allows you to automatically backup your files and drafts to Google Drive. Best regards,
