Add to Home Screen
On iOS Safari or Android Chrome, use Add to Home Screen for an icon and a full-screen window. That shortcut still opens the same signed-in workspace.
Island and tabs
The island stays on screen: Settings, Projects, Scheduled, Tasks, Shared, Search, and Add. Tabs wrap to the narrower layout. Search still uses Search documents….
Touch editing
Notes, tables, and draw are usable on a phone. For long writing sessions a larger screen is easier, but projects, tasks, and comments work in a pocket-sized window.
