Doom Coder sends a notification to your iPhone and iPad the moment your AI coding agents finish, fail, or stop to ask for approval — so you can start a long run, walk away, and trust your phone to call you back. It pairs with the free Doom Coder app for Mac, which watches your agents and keeps your Mac awake while they work. When an agent needs you, the alert reaches your phone in seconds. WORKS WITH YOUR AGENTS Doom Coder understands the events from Claude Code, Cursor, VS Code Copilot, Copilot CLI, Windsurf, Codex CLI, and opencode. You choose exactly which events alert you — completed, failed, waiting for approval, waiting for input — and mute the rest. USEFUL THE SECOND YOU OPEN IT No account. No sign-in. No Mac required to get started. • Prompts — A prompt refiner, not a chatbot. Type a rough request and get back a clean, structured prompt you can paste straight into your agent. Keep refining over follow-up turns, and pull from a built-in library of developer prompts grouped by Refactor, Tests, Debug, Review, Explain, Git, Docs, and Scaffold. • Notes — On-device notes with checklists, reminders, pinning, and search. Turn any note into a prompt with one tap. • Dashboard — Once you pair a Mac, see every agent's live status and drive the Mac's keep-awake controls from your phone. PRIVATE BY DESIGN No servers. No analytics. No tracking. Everything you write stays on your device. When you pair a Mac, sync happens only through your own private iCloud account using Apple CloudKit — your data is never visible to us or anyone else. ON-DEVICE OR BRING YOUR OWN KEY The prompt refiner runs on Apple Intelligence entirely on your device, so nothing leaves your phone. Prefer your own model? Add an OpenAI or Anthropic API key — it is stored only in your device's Keychain, and only the text you choose to enhance is ever sent. Enhancing is always optional. BUILT FOR iOS 26 AND iPadOS 26 A native interface with the system Liquid Glass design, a macOS-style sidebar on iPad, and time-sensitive notifications that reach you even through Focus. Doom Coder is open source. Source, documentation, and support: github.com/katipally/Doom-Coder

BYOT is a native client for OpenCode, the open-source coding agent. Connect to the OpenCode server running on your own computer and drive coding sessions from your iPhone or iPad. Browse projects and sessions, send prompts with photos or files, and watch assistant text, reasoning, and tool activity stream live. Inspect tool inputs, progress, output, and errors. Answer permission requests and questions from your server, queue follow-up prompts, and choose models from your server's catalog. Review session diffs when your server supports them. Switch between saved servers, group sessions by project or browse them in one list, and find sessions by title, project, or path. Unsent text and attachments stay on this iPhone across session changes and app relaunches. Choose System, Light, or Dark appearance. With the optional BYOT companion running on your computer, get notifications for approvals, questions, completed turns, and errors. Enable the computer queue to keep accepted prompts running in order while BYOT is closed. Your computer must remain awake and the companion connected. Work that has not finished uploading needs BYOT to reconnect; uncertain delivery requires your review. BYOT supports OpenCode 1 and OpenCode 2 beta servers with automatic protocol detection. Available features depend on the server version; some OpenCode 2 beta servers do not expose per-session diffs. Your server does the work. BYOT renders its responses and sends your instructions over HTTPS. There is no BYOT account or sign-up, and BYOT has no analytics or tracking. Server passwords are stored in the iOS Keychain. In direct mode, prompts and attachments go to your configured server and the model providers you enable there. Optional notifications and the computer queue use the BYOT relay for device registration, delivery, and encrypted queued content. See the privacy policy for storage and retention details. Requires an OpenCode server you operate, reachable over HTTPS, for example through Tailscale. Notifications and the computer queue also require the BYOT companion. BYOT is an independent client and is not affiliated with the OpenCode project.
