I have used this app many times and it is very helpful
It has a field to allow input of circular mils per Amp to evaluate PCB trace widths based on square mil cross-sectional area. The guys at Black Cat Systems were very responsive to this feature request. They had it up within days. Great job!
The screen shots show the entire app you are paying $2.99 for, so you can't say you were cheated. That's all there is: a very simple calculator of voltage drop in a wire, given gauge, length, and amp load, and a printed table that shows the physical size of a wire gauge (seldom useful: if you are using big wire sizes, you already know how much area to allow for the wire). THAT'S THE WHOLE APP. This is WAY, WAY overpriced, for an app that is too simple for an electrician, and too much odd information for a DIYer. This is a Bad Job. The real ripoff is that I assumed that anything so expensive must have more value. Not true in this case.
Need to compute the electrical resistance or voltage drop of a wire or cable? Now there’s no need to carry lookup tables with you, and calculate value...
