qonverter


Very simple and easy to use desktop calculator.

Latest version is: 1.0.8-alpha

Qonverter is simple and easy-to-use unit & currency converter and calculator. It tries to stay as simple as possible and it does NOT target at advanced users. Qonverter is based on these libraries: * Qt * muParserX
