Typical response time: within 24–48 hours. Please include your macOS version and details of the simulation.
Open the Library view using the toolbar button. Browse our catalog of 40 pre-verified machines, select the one you wish to test, and click Load machine. In the simulation view, enter an initial tape sequence conforming to the active alphabet, then press Start for continuous animation or Step to advance one cycle at a time.
In deterministic Turing machines, the engine checks the current state and the tape character underneath the read head. If no transition rule is defined in the table for this specific (state, symbol) tuple, execution halts immediately. In classical computability theory, halting represents the intended completion of an algorithm.
All custom algorithms are saved in your app's isolated local SwiftData store. You can create portable backups at any time by clicking Export in the toolbar to save standard .json archives. To restore machines on another Mac, use Import.
The tape is logically infinite in both directions. Unwritten cells are filled with the blank symbol _. You do not need to explicitly declare _ in your alphabet list; the engine automatically handles it as an intrinsic blank marker.
No. Turingly operates 100% offline. It contains no network listeners, no outbound telemetry sockets, and no remote dependencies. All computations and file saves occur strictly on your local Mac.
