Easier shortcuts.

Every function has a shortcut. They are easy to remember and easy to press with one finger.

So no more pressing shift for the basic stuff:

Multiply	Add (optional)
(	)

And you can easily get all other functions via
Double Key.

Everything is saved.

Never again worry about losing your calculation or result. Magic Number automatically saves your work and other data. All without getting in your way.

So next time if you accidentally deleted the result or closed the window in the middle of a calculation, you can get back to where you were in no time.
