ASM 8086 Emulator & Compiler vs Run

Master the foundations of computer architecture with the most comprehensive 8086 assembly environment for mobile and desktop. This app transforms your device into a powerful 16-bit workstation, allowing you to write, compile, and debug x86 code without the need for complex virtual machines or DOSBox configurations. Technical Capabilities • Fully integrated 8086 CPU emulation supporting over 60 essential instructions. • Built-in NASM-compatible assembler for instant execution. • Real-time disassembly view to bridge the gap between source code and machine language. • Authentic 1MB memory mapping simulating a true real-mode environment. Advanced Debugging Suite • Precise control with breakpoints and single-step execution. • Live register monitoring for AX, BX, CX, DX, SP, BP, SI, and DI. • Visual FLAGS register tracking (Carry, Zero, Sign, etc.). • Deep memory inspection with a hex-based editor. • Execution logs to trace every instruction cycle. Hardware & System Services • BIOS INT 10h support for screen control, cursor manipulation, and scrolling. • DOS INT 21h support for keyboard input, string output, and program termination. Optimized for Learning • Pre-loaded templates ranging from basic logic to complex algorithms. • Syntax-highlighted editor optimized for low-level coding. • Native performance across iPhone, iPad, and Mac with keyboard shortcut support. Perfect for CS students, OS developers, and retro-computing enthusiasts seeking to understand how software interacts with hardware at the lowest level.

Run-C is a hands-on way to learn and practice the C programming language right on your iPhone or iPad, completely offline. Write real C code, tap Run, and see your output instantly. No internet, no accounts, and no complicated setup. Whether you are taking your first steps in programming or brushing up on the fundamentals, Run-C gives you a focused environment to experiment, make mistakes, and learn by doing. GUIDED LEARNING PATH Run-C includes 15 ready-to-run example programs organized into a Beginner Path that builds your skills step by step: - Hello World: your first program and printf - For Loop Sum: loops and integer math - If/Else: branching with conditions - Countdown: while loops and decrement - Multiplication Table: nested output in a loop - Average, FizzBuzz, Max of Three, Factorial, Power - Prime Check, GCD, Fibonacci, Hex and Char, Collatz Steps Each example comes with a short description so you understand what it teaches before you run it. A REAL CODE EDITOR - Syntax highlighting for keywords, comments, and strings - Line numbers with a clean gutter - Smart auto-indentation on new lines - Automatic bracket, parenthesis, and quote pairing - A dedicated C-symbol keyboard bar for fast access to common symbols - Live line and character counts INSTANT OFFLINE OUTPUT - Runs your C program locally on device, no network required - Clear Output console with selectable text - Separate Warnings tab that surfaces issues without cluttering your results - Error lines highlighted directly in the editor so you can find and fix mistakes fast - Run timing so you can see how quickly your program executes PRIVATE BY DESIGN Your code never leaves your device. Compilation and execution happen entirely on-device, so you can learn and experiment anywhere, even without a connection. WHO IT IS FOR - Students learning C in school or on their own - Developers who want a quick scratchpad for small C snippets - Anyone curious about how programming works, in a friendly, no-pressure environment Run-C focuses on core C language constructs for learning: control flow, numbers, strings, and basic I/O with printf. Some advanced features and system-level APIs are intentionally not supported on iOS. Questions or feedback? Email kshravi86@gmail.com.
