Apippa‑Custom Price Calculator

The app did not display the calculator as desired. I admit that I was using it for general calculations display, and it is possible that my problems were user error. When I just about had it customized to display as desired, it no longer displayed the calculators at all. Deleting and making new calculators did not fix it. Deleting and creating new products did not fix it. Uninstalling and reinstalling did not change anything.
The user interface is more than adequate. It is not polished. It was fairly easy to create calculators once I understood the mechanics.
It is more customizable than the other options, which is why I tried it.
I can't rate it higher because it did not do the thing I installed it to do. Ultimately I sought a custom solution.
