Game Changer
The calculator has been able to do everything I need. It was easy to set up and begin working with right from the beginning, however I recommend the concierge service which saved me time and ensured that the calculator looked and worked exactly how I wanted it to. The support team have been excellent.

Unmatched calculation functionality
I tried 5-6 different calculator forms. Nothing came close to the intuitive formulas and calculation capability of ConvertCalculator.
