Your attention does not stop at the laptop lid. Tabby Sidecar is the queue and the clock in your pocket, live today at every phone browser: sign in with your Tabatha account, see the same queue and active focus the extension sees, start an intent by typing or by voice, and get a Chaperone nudge if you wander off mid-focus. It reads and writes the same account data as the extension and the desktop companion through Cloud Sync, so a checkpoint logged on the phone shows up everywhere within a second. Nothing here is a native app yet - it is a React Native Web app, installable to your home screen as a PWA - but it is not a mockup either. Every card below is the real, shipped UI.
Open tabatha.pondocean.co/sidecar, sign in with Google or a magic link, and the same account the extension knows about is already there - queue, active focus, backburner, tasks. Add it to your home screen for the app feel: it installs as a PWA with its own icon and no browser chrome, updates itself in the background when a new version ships, and lands on a recovery screen instead of a blank one if it ever crashes.
The phone inverts the extension's problem. In the browser, Tabatha has to ask what you are doing because a tab cannot tell it; on a phone, the thing that is missing is not information but presence - the app has to be there the moment you go quiet, and gone the moment you do not need it. So the built half leans on voice and proactive nudges rather than dashboards. The stages here render Sidecar's own tokens (accent #00E0D6) and its 6/10/16/999 radius scale - a different app from the extension and the desktop companion, and it does not pretend otherwise.
