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.conf only 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: in the iOS app tap Add Mac, and enter the 8-character code shown in the Termio menu-bar app on your Mac.

Get the Termio iOS app

Steer your coding agents from your iPhone — watch live terminal output, answer approval cards, and switch between panes on the go.

Coming soon to the App Store

Get the Termio Android app

Same pocket terminal experience on Android — pair with your Mac, watch live panes, and respond to approval cards on the go.

Download Android (.apk)

Sideload install: after download, tap the APK and allow install from your browser if Android prompts. Release-signed; requires Android 8.0 or later.

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.
