There's an old saying about cameras that also applies to calculators: "The best camera is the one you have with you."The same is said about firearms.
Thank you, FRiend. I just bought the app....It doesn't flash 'running' like the original 12C did when it calculates the IRR but otherwise it's AWESOME, TOTALLY AWESOME!!
It is also beautiful...like a piece of good modern art.
Glad you like it! It is a great piece of work and you instantly know how to use it. Can’t beat that! I love RPN and use it all the time. I totally forgot about the flashing “Running” 😊
