Turing Machine Simulator2.5 - App Store
You'll be able to see results in few seconds.
Publisher Description
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.
Version History Support for the new iPhone Duo added 2.5 Oct 7 - Support for iOS 26 (Liquid Glass) added
- Support for dynamic fonts (accessibility features) added
- Bugfix: fixes an issue where the tape inscription of an tape that is infinite on both sides was only preserved for one side, after a turing program has finished running (this is usually not critical, because for a new run you would normally create a new tape inscription instead of reusing the old one) 2.4 09/15/2025 Fixes some visual issues in dark mode 2.3 02/09/2024 - Makes it easier to enter states while defining new instructions: Already existing states can be now simply picked from a popup menu by pressing the "+" button. So you don't have to enter these via keyboard again.
- Fixes an issue with wrong "endless loop" messages under certain conditions.
- Fixes an issue with changes in text field being not retained when directly leaving the view without confirming with the "return" key 2.2 01/24/2024 Support for new devices added (iPhone X, XS, XS Max, XR, iPad Pro) 2.1 11/15/2018 - The App is now universal and runs on iPad, iPhone and iPod Touch
- Updated for iOS 8
- Supports the new larger iPhone 6/6 plus devices 2.0 01/27/2015 Fixed a bug for turing programs which use a tape that is infinite on both sides. Crossing the starting point of the tape to the left didn't always work correctly. 1.0.5 03/01/2010 Fixes a bug which could cause a crash after reseting a turing program. This could happen only when a turing program has written something on a tape (which is infinite on both sides) to the left of the starting position. 1.0.1 04/05/2009 1.0 01/28/2009
