Turing Machine Simulator vs Smith Chart Touch
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Turing Machine Simulator
This application simulates Turing Machines, a fundamental concept in computer science and mathematics for analyzing algorithm computability. It offers a digital alternative to paper-and-pencil simulations, allowing users to write, execute, and analyze programs step-by-step with adjustable execution speeds.
- Turing Machine simulation
- Program execution and analysis
- Step-by-step execution
- Adjustable execution speed
- Export/import programs via email
- Includes example programs

This app is a Turing Machine Simulator. Students of computer science and maths are probably familar with Turing Machines, because the Turing Machine is one of the important models when analyzing if mathematical problems or algorithms are computable. Usually dealing with Turing machines requires paper and pencil for simulating the program execution. This app can help by providing several ways to execute Turing programs and analyze it in an easy and comfortable way. You can write new programs for the Turing Machine, execute them and analyze the execution even step by step. It's also possible to change the speed of the execution. It's possible to export and import Turing programs using email. The app comes with some example Turing programs to play with.
Smith Chart Touch

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.
