About

Termcorp

Read full description

Termcorp turns your iPhone and iPad into a window onto the coding agents running on your Mac. Your work lives in tmux, not in the app. Termcorp opens an SSH connection to your Mac (or any server), attaches a persistent tmux session, and mirrors the terminal. Close the app, lose the network, lock your phone - nothing stops. Reopen it, and you're right back where your agent left off. Built for developers and vibe coders who run AI agents in the terminal. WHY TERMCORP - Persistent sessions: your agent runs inside tmux on the Mac. The app is just a viewer; the work never stops. - Session recovery: open the same session on another device; it switches over, resizes, and the other view detaches. - Voice dictation: speak your prompt; it goes straight to the terminal. No copy-paste. - Attachments: photos, screenshots, PDFs and files land in your project, with the path inserted for you. - Built for touch: esc / ctrl / arrow key bar, swipe to scroll history, a keyboard you can tuck away. - Encrypted SSH: connection keys are stored in the iOS Keychain, never in the clear. The app has no servers and collects nothing. WORKS WITH ANY CLI Termcorp is a terminal. It drives whatever runs in it - Claude Code, OpenAI Codex, Gemini CLI, Aider, or a plain shell. FREE ON MAC Termcorp for Mac is a free companion app: a local terminal for your desktop. Termcorp for iPhone adds the mobility - pilot your agents from anywhere. Learn more at terminal.emcorp.io REQUIREMENTS A Mac or server you can reach over SSH, with tmux installed, on your own private network (e.g. Tailscale). SUBSCRIPTION Termcorp is free to download, with a 7-day free trial. Full access then requires a monthly subscription. The subscription renews automatically unless cancelled at least 24 hours before the end of the period; manage it in your App Store account settings. Termcorp is an independent product, not affiliated with Anthropic, OpenAI or Google. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
