About

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.

Highlights
  • 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.

The LogicGateDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse and simplify logic gate networks. You can draw logic gate networks and share it with others. You can generate truth table and find simplified/minimized boolean expression that represents the network. You can optimize and reverse engineer a boolean expression to draw a ladder logic diagram. It performs both forward engineering (boolean expression to logic circuit) and reverse engineering (logic circuit to boolean expression). There can be multiple groups of network and each group can have multiple outputs. Truth table is generated for all the outputs. You can simplify a boolean expression, and find the truth table and share it. Show truth table along with different types of boolean expression (simplified, Sum-of-products, Product-of-sums) The simplified expressions also gives you the number of gates required. You also get the alternate expressions for the same output with the gates required for that. You can generate a truth table, simplified boolean expression using input-output waveforms. You can generate a output waveforms, simplified boolean expression using truth table and input waveforms. You can generate a grey codes and grey code encoder wheel and share it. Do you have a truth table for your network and want to find the simplified/minimized boolean expression? This app has you covered. You can simulate your network by changing one input at a time or toggeling all inputs at once. This app generates beautiful diagrams (logic gate diagram or waveform diagram) that you can share with others or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a page to help you study. This study tab teaches you some very important boolean algebra theorems. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

Verdict

The call

The clearest difference is review sentiment: Turing Machine Simulator at 100% against Logic's 0%. Turing Machine Simulator also leads on price ($2.99 vs $5.99) and iOS requirement (12.0 vs 15.1). Logic's advantage is update cadence (every 5 weeks vs every 19 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
