Smith Chart Touch
Read full descriptionHide full description
Smith Chart Touch is the essential Smith chart tool for RF and microwave engineers, students, and hobbyists. Design and analyze impedance matching networks interactively — directly on your device. Build your circuit by adding components one by one and watch the matching path update on the Smith chart in real time. Tap any component to edit its value, drag on the chart to tune it visually, or type exact numbers — the chart and inputs stay in sync at all times. Circuit Components: Series resistor, inductor, and capacitor Parallel resistor, inductor, and capacitor Transmission line (length in wavelengths) Open and short stub (parallel) Smith Chart Modes: Impedance (Z) chart Admittance (Y) chart Immittance (ZY) combined chart Key Features: Fully interactive: drag on the chart or type values — both update each other instantly Multiple projects with custom names and colors per circuit path Example circuits included to get started quickly Clean, dark UI optimized for readability Who is it for? Smith Chart Touch is built for electrical engineers working with RF circuits, antenna design, amplifier matching, and transmission line theory. It is also a great learning companion for students studying microwave engineering.

Verdict
The clearest difference is price: Smith Chart Touch at Free against ASIC & FPGA Design Studio's $2.99. Smith Chart Touch also leads on iOS requirement (15.0 vs 17.0). ASIC & FPGA Design Studio's advantage is update cadence (every 3 weeks vs every 3 months). On ads, in-app purchases and device support there is nothing between them.
