Calculating has never been so timelessly beautiful and efficient at the same time.

You can transform the realistic look into a stylish theme at any time (even in the middle of a calculation), just as you like.

Real Theme Calculator Pro has been designed so that both the aesthetics and usability resemble a real handheld calculator. It includes all scientific functions plus 4 number systems for number enthusiasts. It supports binary, decimal, octal and hexadecimal calculations.

Real Theme Calculator Pro is very easy to use.

The completely ad-free Pro version includes 7 switchable themes and an integrated help page. Furthermore, all future developments (themes, fonts, mathematical functions, etc.) are included free of charge after purchasing the Pro version.
