Your Mac. From your pocket.
Terminal, remote desktop, and file explorer. All from your iPhone. End-to-end encrypted. No ports to open. No data we can see.
Coming soon for macOS + iOS
Work from anywhere
Stand up. Walk away. Keep working.
Your sessions run in parallel on your Mac and your phone. Pick up mid-task from wherever you are. The terminal you left open, the screen you were sharing, the files you were browsing. Nothing is lost. Nothing to restart.

Terminal
Full shell access
Your tmux sessions run on your Mac. Pick them up from your phone exactly where you left off. Same scroll position, same working directory.
Desktop
Screen share
See and control your Mac's entire screen from your phone. Click, scroll, and drag. It all works like you're sitting right in front of it.
Files
File browser
Browse, open, and transfer files between your Mac and your phone. Your entire filesystem, right in your pocket.
All sessions persist. Switch devices whenever you want.
How It Works
Three steps to seamless access
No complex networking. No VPN configuration. Get connected in under two minutes.
Install the agent
A lightweight menu bar app runs on your Mac. No ports opened, no firewall rules. It connects outbound to our relay and that's it.
Pair your device
Open the iOS companion app and pair securely. Both devices verify a shared code on-screen so no one can intercept the connection.
Connect instantly
Open a terminal, share your screen, or browse files. Everything is encrypted end-to-end. If you disconnect, your sessions persist and are waiting when you return.

Encrypted by design, not by promise
We didn't bolt security on as an afterthought. The architecture makes it impossible for anyone, including us, to see what you're working on. Your keys never leave your devices. Your sessions are yours alone.
Only your devices hold the keys
AES-256-GCM encryption
Every byte between your devices is encrypted with military-grade AES-256-GCM. Keys are derived per-session using ECDH and never leave your hardware.
Zero-knowledge relay
Our servers route encrypted packets but cannot decrypt, read, or store your terminal content. We architecturally cannot access your data.
Verified pairing
Device pairing uses Short Authentication String verification. You visually confirm a code on both screens, preventing any man-in-the-middle attack.
No open ports
Both your Mac and iOS device connect outbound only. No firewall rules, no port forwarding, no attack surface exposed to the internet.
