OSH vs Run

OSH turns your iPhone into a hardware-backed approver for zero-trust SSH access. Instead of long-lived SSH keys scattered across laptops, your team's gateway issues short-lived SSH certificates only after a human approves each request. OSH is where that approval happens — on a device you carry, protected by Face ID and the Secure Enclave. HOW IT WORKS • Enroll your device by scanning the gateway's QR code. • When someone requests SSH access, OSH shows you who, what, and where. • Approve or deny with Face ID. Your approval is signed by a key that lives only in the Secure Enclave. • The gateway issues a short-lived certificate — no standing keys, no shared secrets. WHY IT'S SECURE • The signing key is generated inside the Secure Enclave and is non-exportable — it can never leave your iPhone. • Every approval requires biometric authentication. • OSH connects only to the gateway you configure. It has no analytics, no trackers, no ads, and no third-party SDKs. FOR TEAMS • Role-aware: signers, admins, and root see the controls appropriate to them. • Review access rules, approval history, and gateway logs from the app. OSH requires a compatible zero-trust SSH gateway to connect to.

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.
