Features & Capabilities

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.

I can’t put a name for a program I create, and I can’t modify its alphabet. I’m supposed to be able to but the changes are not saved. This surprised me because it’s a sleek app otherwise. I’m hoping this will be fixed quickly and I will revise my rating if so. Not good for a paid app to have showstopper bugs like this. EDIT: I figured out that I wasn’t tapping DONE. If you edit the name or the alphabet, and tap away to a different section, the changes will be SHOWN on screen still but will not be saved. I still think this is a bug, but there’s a workaround (just tap DONE after each edit) so it’s not a showstopper. Upgrading my rating therefore.

I've tried a few other Turing sims and this one is the best so far. It's pretty flexible and relatively intuitive to operate with decent documentation and links to more information. The examples are pretty neat and are even commented. Overall, a nice app for the price.
