SmithChart April 2021   (details) Prime ENG   379KB/408KB
ScreenshotDisplays a Smith chart and if you tap a point will display many of the relevant data about that point, including Z, X, Gamma, Return Loss, VSWR and Q. Modified to be an app that expands to fill the display, inverting the cursor, and more. Gives the usual Smith chart results just by clicking on the chart. Also, up to 3 parameters can be clicked to select colors and when "Gradient" is clicked, the gradients in the selected colors are plotted. Much faster than the previous version.
