Sell a preconfigured wall-mounted planning display with a focused household interface and optional phone access. It would combine shared calendars, recurring chores, fortnightly schedules, notes, and priority reminders while supporting an offline fallback and a one-time hardware purchase. The initial product can use commodity display hardware, with the business providing the planning software, household setup, calendar migration, and ongoing optional support.

Calendar usage is spread across phones, computers, work accounts, and dedicated household devices, while buyers increasingly expect synchronization without another mandatory subscription. Commodity tablets and low-power displays make a narrowly focused household appliance feasible for a small operator to assemble and validate.
