Create a family chart in the app, print it for the fridge, then update chores with taps or Siri as life happens. Kids keep using the page.
Kids use the page. Grown-ups use the app.
Eight can do most of what an adult considers a real chore, just slower. Pack lunch, empty the dishwasher, fold a load of laundry, take out recycling, wipe the counters, walk the dog. Twenty minutes of reading and twenty of piano belong on the chart too. Star values start to matter — bigger jobs earn more.
Seven to nine. By eight the kid can read across a row, count their own stars, and see what is still open without waiting for a parent to narrate the list.
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.
