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 lack of an option to alter the tape alphabet of the computational models created in this app, makes it simulate something like a Pushdown Automaton and not a Turing Machine if any kind. It seems that it is also not possible to create multi-tape Turing Machines and name of the states are forced to be uppercased, which is only somewhat of an annoyance. There is an inherent lack of error messages in the UI, which makes it rather difficult to spot when something has been done erroneously. I bought the app since it seemed to offer the possibility of using it in Split View, but attempting to do so makes the app crash. I would definitely recommend against buying this app, until it has received updates such that it actually simulates a Turing Machine or some sort. Until that I would suggest striving for the free alternatives available in the App Store.

- 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)
