ConKarma is built for the way co-parented households actually work — one shared spine across two homes, not one app on Mom's phone or one app on Dad's. Each adult creates their own private Cell, and kids join both via invite; they see one consolidated experience, but their data stays scoped to whichever Cell they're acting inside. A custody-aware calendar marks whose home each day is on, fires pick-up reminders only to the parent dropping off, and layers under regular events.
Privacy boundaries hold between the adults: what you do in your Cell — your journal, your reward catalog, your DNA — stays in your Cell, and the other parent sees only the cross-Cell shared layer like the calendar and kid mission progress. Subscriptions are separate too, so there's no shared payment, and kids in both Cells inherit Family-tier benefits without paying twice.
