Create your family chart in the app, print it for the fridge, then keep it current with taps or Siri. Kids keep using the page. Android follows Play Store readiness.
The paper stays. The parent phone keeps up.
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.
