Create your family chart in the app, print it for the fridge, then log chores with Siri or a tap. Kids keep using the page. Parents get the bookkeeping help.
The paper stays. The bookkeeping is ours.
Ten can vacuum a room, run a load of laundry from start to finish, watch a younger sibling for half an hour, cook a simple breakfast. The chart is no longer about whether they can — it is about whether the family remembers to ask. Keep the star column; it still works at this age.
Eight to ten. Add one or two stretch chores with bigger star values. A vacuumed room or a folded basket is worth more than a made bed, and the chart should say so.
Stars are a record, not a currency. Use them to see what happened during the week. If your family pays for bigger extra jobs, keep that rule separate from ordinary family responsibilities.
