MultiCalc: All-in-1 Calculator

MultiCalc is a powerful, comprehensive, well designed set of calculators. The standard and scientific calculators are free. A one time charge of $6.99 adds unit conversions, financial, fractions, currency conversions, tips, and programming. You can choose 4 calculators to be used simultaneously. The User Interface is intuitive, visually attractive and enables excellent ease of use of the rich set of functions.

I only scratched the surface of what this calculator can do. I find it essential for conversion of so many different units. It’s also amazing when traveling either in the destination country or for booking international flights in their local currencies. Highly recommended.
