JACK Mobile

Jack Mobile is the companion app for JACK — the desktop session manager for AI coding agents. Stay connected to your sessions wherever you are.

When the agent running on your Mac needs your approval to execute a command, edit a file, or choose between options, Jack Mobile delivers a push notification with action buttons. Tap Allow, Deny, or pick an answer directly from the lock screen, without opening the app.

KEY FEATURES

• Inbox of pending requests — every permission and question waiting on you, in one place • One-tap actions — approve or deny straight from the notification, even with the screen locked • Answer prompts on the go — respond to branching questions when the agent needs a decision • Workspaces and sessions — browse ongoing work, follow conversations, see recent activity • Multi-workspace, multi-session — handles parallel projects and concurrent agents • Provider-agnostic — works with whichever coding agent JACK is configured for on your Mac • Private by design — traffic flows over your own private overlay network, never through our servers • Dark mode native — built for late-night sessions

HOW IT WORKS

1. Install JACK on your Mac.
2. Make sure Tailscale is running on both your Mac and your phone, on the same tailnet.
3. Open Jack Mobile and scan the QR code from the JACK pairing dialog.
4. You're paired. Notifications arrive whenever your agent needs you.

REQUIREMENTS

• A Mac running JACK desktop. • Tailscale installed on both devices (free for personal use). • An internet connection for push delivery.

PRIVACY

Your agent's prompts, files, and outputs never reach our infrastructure. Pairing and command flow happen over your private network. Only push delivery uses Apple Push Notification service. The device token and server fingerprint are stored in the iOS keychain.

Jack Mobile is for developers who use AI coding agents and don't want to babysit a terminal all day. Spawn sessions on your Mac, get pinged when input is needed, decide on the move.
