SophiCalc

SophiCalc is an advanced yet easy to use calculator app.


General Features:
• Perform calculations with arbitrary complex mathematical expressions.
• Editing expressions made easy: Position the cursor without restrictions using the build-in magnification glass.
• Reuse previously entered expressions via calculation history.
• Freely mix the use of arguments in radian or degree for trigonometric or hyperbolic functions in one expression.
• Efficient implementation for fast execution and small program size.
• Simply touch the result or the equal sign to perform further operations:
- Define your own named constants.
- Send calculations as e-mail.
