I haven't used them extensively but they seemed to have extremely clunky UI and werent very user friendly. Usefull as its interactive smith chart automaticly shows the steps for real component values, the demo version is free but limited to only 5 componentsīig expensive commercial software suites, both ADS and Microwave Office have their own smith tools.
Decent tool, noteable is the large amount of available components and simplicity in importing custom s2p files Looking through the subreddit I have found some recomendations for the most common ones but I recently came across a new one with some interesting features (point 5).
Over the last couple of years I have been using various smith chart tools/apps, each of which have been lacking in one way or another.
