Everything, not a viewer
The whole thing in your pocket, not a read-only companion.
Motion's own mobile app is view-only, and it's the thing its users complain about most. If you can only change the plan at a desk, the plan is stale by Tuesday lunchtime, because the day goes sideways while you're away from the desk. Every screen here changes something: set up a repeat, rewrite a schedule, connect a calendar, fix a length you got wrong this morning.
How to use it
The tabs are Today, Inbox, Tasks and Settings. Today has two views — the agenda, and the day drawn to scale — and the button in the top right swaps between them. Tasks carries a toggle for All tasks and Repeating. Settings opens Calendars, Hours and Templates above the preferences.
The honest version
Built and tested screen by screen against a seeded server, and running on one real iPhone. Nobody has leaned on it for a full week yet.
