Termio

Quickstart

Up and running in minutes.

Download the Termio Mac app and launch it. It brings tmux and the Termio daemon along for the ride — then drive whatever agent you run in your panes: Claude Code, Cursor, Codex, or Gemini. It sets up a starter ~/.tmux.confonly if you don't already have one.

Install the Mac app

  1. Download the Termio .dmg for macOS.
  2. Open it and drag Termio into Applications.
  3. Launch Termio — the background daemon starts automatically.
Download for Mac (.dmg)

Then pair your Mac from the iOS app → Settings → Pair a Mac.

The five tmux commands you need

tmux is the terminal multiplexer Termio attaches to. You do not need to learn it — just these five.

  • tmux attach -t claudejoin your claude tmux session
  • Ctrl-b, then ddetach (leave session running)
  • Ctrl-b, then cnew window
  • Ctrl-b, then nnext window
  • Ctrl-b, then %split pane vertically

Then start your agent

  1. Attach to the session the Termio app created: tmux attach -t claude
  2. Launch your agent — type claude, cursor, codex, or gemini and press Enter. Your iPhone is now wired up.
