pocket/grammer vs Codable

Your phone is now a full coding environment. PocketGrammer runs AI coding agents with open models that live entirely on your device — no account, no cloud required — and shows you what it built in a live preview, right on your screen. AN AGENT THAT PLANS, THEN CODES - Ask for a feature in plain language. PocketGrammer asks clarifying questions, then writes a step-by-step plan you can review before a single line changes. Hand the plan to code mode and watch each step execute — with history for every file it touches. REAL MODELS, REALLY ON-DEVICE - Download open models sized to your device — Qwen 2.5 Coder, Qwen 2.5 Instruct, Qwen 3, and SmolLM2 — and run them entirely offline. Your code never leaves your phone unless you tell it to. A REAL WORKSPACE - Multi-tab code editor with syntax highlighting and autocomplete • Diagnostics that catch syntax errors and unbalanced brackets as you type • Regex-powered search across every file in the project • A file tree you can drag to rearrange, with rename, copy, and delete • File history: step back to any earlier version of any file LIVE PREVIEW - Run web projects instantly in the built-in preview. Switch between fit, mobile, and tablet viewports, and watch console output and errors in a dedicated panel — the preview reloads automatically as the agent writes code. GITHUB IN, CODE OUT - Browse a GitHub repository and import its files into any workspace, then let the agent build on them. BRING YOUR OWN KEY - Prefer frontier models? Add your own API keys for OpenAI, Anthropic, Google Gemini, OpenRouter, or a custom OpenAI-compatible endpoint (LiteLLM works great). Keys are stored securely on your device, and you choose which role — planning or coding — uses cloud versus local. YOUR DESKTOP, PAIRED TO YOUR PHONE - Open your workspace in any browser on the same network and keep using the IDE you love — VS Code, Cursor, or any of them — with your phone doing the AI work. One-time purchase, unlimited devices on your Apple ID. FREE TO START, YOURS FOREVER - Every mobile feature is free. Desktop Access begins with a 7-day free trial, then unlocks with a single $19.99 purchase — never a subscription. PRIVACY FIRST - No account required. On-device models work in airplane mode, and cloud providers are only called when you choose them.

Codable turns programming practice into a habit. Solve focused challenges in ten languages — from your first data structure to lock-free concurrency — and build real fluency one problem at a time. WRITE REAL CODE IN 10 LANGUAGES C, C++, C#, Go, Java, JavaScript, Python, Rust, Swift, and TypeScript. Switch languages anytime — solve the same challenge in Python today and Rust tomorrow. GO DEEPER THAN SYNTAX Challenges span the topics that actually make you a better engineer: • Fundamentals and string manipulation • Data structures and algorithms • Recursion and functional programming • Object-oriented design and generics • Error handling, concurrency, and memory management BUILT FOR EVERY STAGE New to programming? Start with fundamentals and level up steadily. Experienced? Jump straight into concurrency, memory management, and the problems that show up in technical interviews. PRACTICE THAT STICKS Short, focused challenges designed to fit into a daily routine — because fluency comes from reps, not marathons. Download Codable and start mastering your chosen language!
