QuickCalc is a powerful, tiny calculator application which calculates as you type! Extremely tiny and simple to use yet with advanced Excel-like functions. Installs no messy DLLs or spyware, doesn't require VB, Java runtime libraries and contains anti-virus mechanisms to prevent trojan infection (which makes it safe to share). QuickCalc makes a perfect Windows calculator replacement. QuickCalc is a tiny self-installing/uninstalling executable to reduce overhead. It has no DLL or runtime dependencies and contains anti-virus mechanisms to prevent trojan infection (which makes it safe to share). It has full keyboard-shorcut support for all functionality including F1 html-page help which explains the basic and advanced functions and provides an animated demonstration. The shareware license is only requested if the program is used extensively (appr 60 days) otherwise, the user will never even know its not freeware.
