New in 2.5: on-device voice input, Markdown preview, and smoother pane switching, restore, and reconnect.
Built for tmux. Built for AI coding agents.
Attach is a native tmux client for iOS, made for developers running Claude Code, Codex, OpenCode, and similar tools on remote machines.
Browse sessions, switch windows, inspect panes from a visual layout, and manage everything from a purpose-built interface. Your terminal state stays on the server. Attach gives you a fast, native window into it.
Why Attach:
- Monitor AI coding sessions on the go
- Native tmux session, window, and pane management
- Visual pane layouts, quick switcher, and breadcrumb navigation
- Smart keyboard with pinned modifiers, trackpad mode, and hardware keyboard support
- 20+ terminal themes, including Dracula, Nord, Tokyo Night, Catppuccin, and Rosé Pine
- Face ID lock and SSH keys stored securely in Keychain
- Notifications for connection events, even in the background
- Adaptive polling for responsive updates without unnecessary battery drain
- On-demand scrollback history
- Paste screenshots from your clipboard directly to your server
- Auto-reconnect that picks up where you left off
No local terminal emulation. No bloat. Just tmux, natively on iOS.
Every other SSH app I use works fine. This one fails to resolve DNS and connections to IP addresses throw TCP errors.
Developer Response
You're right, and thanks for the clear report. This hits IPv6-only and NAT64 networks (common on cellular) and IPv6 hosts - our connection code was resolving over IPv4 only, which is exactly the DNS and TCP errors you saw. It slipped past us because we live in Tailscale and dual-stack Wi-Fi, where the IPv4 path always works, but that's no excuse. We've fixed it to handle both, and it's coming in the next update. Please give it another go when it ships, and reach us at support@arbt.tech if anything's still off. Thanks for helping us catch this.
It works!

So this works as advertised (now). If you see someone’s previous review and the developer’s response it looks like they addressed things and I was able to get this to work. I run a VM with Hermes and Tailscale on it so I can connect to it safely from my phone and laptop. Hermes acts as my system admin, I talk to it from Slack. I only use it to handle updates, starting new tmux sessions, installing packages, etc because it requires tokens. Even with the cheapest model if I were to use it as designed it wouldn’t be worthwhile (to me).SO, enter Attach. I start tmux sessions either from my laptop or using Hermes. Then I use Attach to connect to a session or sessions and work with Claude Code there.***Edit: the issues I reported below were do to how Claude Code was set to render. For some reason I was configured to use the “fullscreen renderer.” The fix was to run the following in the Claude Code prompt: ‘/tui default’. ***The only reason I didn’t give it five stars is because I would love to be able to hide the keyboard to give me more screen space to read without having to use the pgup and pgdn shortcuts.***It would be nice for a noob to tmux like me if there was a slide out with a cheat sheet of basic commands or helpful tips.I am very happy with this setup and this app. I’m able to step away from a Claude Code session, check up on it away from a computer, and interact as needed to keep things moving. Highly recommended.
This is a big update focused on faster terminal workflows, better agent support, and a more polished mobile experience.
• New Markdown preview support for detected file paths
• New voice input with on-device transcription and voice-to-code post-processing on supported devices

• Added session tree disconnect action and other usability improvements
Thanks for using Attach.
