What it can do
The current mobile client includes:Saved gateways and sessions
Mobile keeps a local list of saved gateways and stores device-session credentials separately in the platform secure store. The visible gateway entry can be edited or removed without showing raw credentials in the UI. Access credentials are short lived and refreshed through the session protocol. If the session is revoked, the app removes it from the active connection and asks you to activate the device again.Remote gateway first
The mobile app currently manages remote gateway entries. It does not install, start, or supervise a local gateway process on the phone. For mobile use, run a gateway on a computer, workstation, server, or other reachable host. Then add it in the mobile app with its address and the one-time activation code created bypioneer device create.
Tool calls, local paths, MCP servers, provider requests, and task execution happen on the gateway, not on the phone. Permission modes and sandbox/resource policy are enforced by that gateway.
Consistency with desktop
Desktop and mobile use the same product concepts. A gateway, workspace, thread, provider, skill, MCP server, task, and artifact mean the same thing in both clients. The difference is responsibility: desktop can install, start, and manage a local gateway, while mobile connects to gateways that already exist.Builds and locales
The mobile app targets iOS and Android and uses the same eight UI locales as desktop: English, German, Spanish, French, Hindi, Japanese, Russian, and Chinese.Related pages
