OpalCalc Comments

Customized and speedy feeling

Positive Comment by jeanhsu
about OpalCalc Oct 2016
  1. Really nice calculator because you can easily add custom functions to fit your style and your job. In my case, as a web developper a function to easily calculate width of an element in a webpage.
  2. Also the mix between text and numbers is awesome because it is easier to make sense of what you just did. For example for some cash spending. Having the label besides the number really helps.
  3. Nifty conversion and calc (goodies) about time and cash rate. Wow, how many times did I check USD to CAD dollars before an online buy.
