From the developer:
Calctor is an advanced calculator with a simple interface. You have an input-region where you enter your calculations, and an output-region where the results of your calculations automatically appear while you're typing. You can format the result using formatters. Also you can use commas as separators between thousands, only if you put the number between single quotes.
You may want to check out more software, such as OC Conversion Pro, LoanExpert Plus or JavaFoil, which might be similar to Calctor.
