It may not be obvious but using a calculator can waste hours of your time and hinder your productivity. Smart Math Calculator has a unique and efficient user-interface that allows you to type in your calculations super fast, avoid common calculation mistakes, and be more productive overall thanks to the following key features:

- Type down equations just as you would in a text document. After each key stroke the result is immediately calculated and displayed. You don't even need to press enter.

- If you make a mistake you can edit the equation just as you would in a text document. The calculated result is immediately updated.

- You can calculate and edit multiple expressions simultaneously.

- Create your own variables and reuse them in upcoming calculations. If you edit the value of a variable, the result of all calculations that depend on that variable will be automatically recalculated.

- With a click of a button you can enable the OnTop feature to keep the calculator on top of other windows so that you can easily copy and paste number between the calculator and your documents.

- Your calculations are automatically saved and reloaded the next time you start the app.

- You can save a bunch of calculations in a file and re-open them later.

- Most other calculators can only handle 15 digits precision whereas this calculator can compute numbers up to 1,000 digits precision.

- For faster access, the calculator can automatically start and run in the background so it can instantly pop up when needed. If you enable this feature, a small icon will always be visible to allow convenient access with a single click.

Free Edition limitations:
- Cannot save and open files
- Cannot print
- Maximum 5 simultaneous math expressions
- Maximum 100 digits numerical precision

Grazillion ,

Great, especially with the ability to Pin it up front but...

The downside is no clear button and no way to use Ans function.

Developer Response ,

Thank you for your feedback. To use Clear button, you can simply click on New File button. To user Ans (answer to calculation of the previous line), please use the ~ operator. For example instead of ANS+5 you should type ~+1

Really misses "Ans" and "AC" buttons

Please add a button to clear any of the equations lines, and another one to use the answer of the last calculation. Even the simplest calculators have those.

Developer Response ,

To use the answer of last calculation please use ~. For example ~+1 will add 1 to the last answer. For your suggestion about adding a button to clear equation, I can certainly add this button but I have few questions. Please email me at
