Turing Machine Simulator vs SlipStick
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.
SlipStick
This app is a fully functional digital reproduction of a classic engineering slide rule. It allows users to perform complex calculations like multiplication, division, logarithms, and trigonometry, just like the original manual tool.
- Virtual slide rule reproduction
- Multiplication and division
- Logarithm calculations
- Trigonometry calculations
- Classic engineering tool

Verdict
The clearest difference is update cadence: SlipStick at weekly against Turing Machine Simulator's every 16 months. SlipStick also leads on price ($0.99 vs $2.99) and iOS requirement (12.0 vs 15.0). Turing Machine Simulator's advantage is review sentiment (100% vs 83%) and rating (4.8 vs 4.6). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
