Couldn’t live without it

I was disappointed to see that I had to pay to go from version 3.9 to 4.0, but I didn’t hesitate to do it. This is one of the best apps in existence, and indispensable for anyone on a Mac who uses a calculator, especially for scientific work. I have a legendary HP 15C but haven’t touched it in years, because I don’t have to take my fingers off the keyoard to use PCalc. Every button has a keyboard equivalent. I work as a physicist and PCalc is full of built-in physical conversions including one, if I remember right, that was added after I requested it from the developer. The appearance is completely customizable so you can turn it into whatever you want. I can’t imagine using a computer without PCalc.
