Smith Chart Touch
Education
Free · Designed for iPad. Not verified for macOS.
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.
