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

Great to have note capability & calc/conversion all in one app. Easy to get started, but lots of options once you're ready for them. No bugs, so far... Many months later; am discovering & using more & more features & functions. With that, I'm more & more pleased w/ Calc Note. It is my go to calculator & conversion HQ. You know an app is fully part of your life when you make reference tables to use frequently. I am nearly done w/ a metric <-> decimal Imperial <--> fractions chart.

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❣️

Pretty good. I have given it a 5* rating, but the pop-up that comes up when I want to refer to a certain result or when I want to enter a function key is super annoying. Remove the pop-up guys! (Or give us an option to turn it off) Edit: There was an option for turning off the pop-up keypad! You guys are awesome, and this is the best calculator ever! Thanks for the good app, and thanks for the reply on my first comment. I bought the pro version to show my gratitude. This app is worthy of every last cent!
