Mac
An interactive Turing machine simulator for macOS. Design transition rules, inspect tape executions step by step, and experiment with 40 built-in algorithms.
Turingly is a clean, interactive Turing machine simulator designed for students, educators, and computer science enthusiasts. Explore the foundations of theoretical computer science through an intuitive, visual macOS experience.
Whether you are studying automata theory, preparing for an exam, or simply curious about how computation works at the most fundamental level, Turingly makes abstract concepts tangible and easy to understand.
KEY FEATURES:
• VISUAL TAPE SIMULATION
Watch the infinite tape and read/write head in motion. Inspect tape cells, track current state changes, and observe every step with clear visual feedback.
• STEP-BY-STEP OR CONTINUOUS EXECUTION
Run machines at your own pace. Step through instructions one transition at a time to debug edge cases, or adjust the simulation speed slider from 50 ms to 2 seconds for continuous execution.
• INTERACTIVE TRANSITION TABLE
Easily configure states and transitions with an intuitive rule editor. Pick states, symbols, movements (Left, Right, Stay, Stop), and validate logic with instant visual feedback.
• 40 BUILT-IN ALGORITHMS
Explore a rich library of pre-configured, tested algorithms spanning key theoretical domains:
- Binary arithmetic (increment, decrement, addition, two's complement)
- Bitwise logic (NOT, AND, OR reduction)
- Formal languages & recognizers (0ⁿ1ⁿ, palindromes, equality checks)
- Tape manipulation (clear tape, center finder, string duplicate)
- Parity & modular arithmetic (odd/even, divisibility by 3)
- Theoretical milestones (Busy Beaver 3-state)
• BUILT-IN COMPUTER SCIENCE GUIDE
Learn directly inside the app. Browse comprehensive offline articles covering states, alphabets, blank symbols, transition functions, and practical design tips.
• MACHINE NOTES & DOCUMENTATION
Attach custom notes, pseudocode, and state documentation directly to each machine so you never lose context.
• IMPORT & EXPORT ARCHIVES
Safely export your custom machines as JSON archives to share with classmates, students, or backup your work.
DESIGNED FOR MACOS:
• Fast, fluid, and native SwiftUI design
• Optimized for Apple Silicon and Intel Macs
• Full VoiceOver accessibility support for tape and rule editors
• Native keyboard shortcuts for effortless simulation control
• Full Dark Mode support
PRIVACY BY DESIGN:
• 100% offline — no internet connection required
• No account, login, or tracking
• Zero personal data collected
