AllSet: School Planner - The school week, shared by parent, child, teacher and tutor

I built this because my own children's school week lived in four places at once: a WhatsApp group, a school portal, a tuition notebook, and whatever my son remembered on the bus. The part that took longest was not the planner. It was working out that four different people need to see the same week differently. A child wants to know what is due tomorrow. A parent wants to know whether it got done. A class teacher wants to publish homework once and know how many finished, without ever opening a named child's planner. A private tutor, invited by the parent, should see that one child's week and nothing else. There are no leaderboards. Points and trophies measure a child against their own record, never against another child. That was a decision, not an oversight, and it is the one I would defend hardest. It is on Google Play and runs in any browser. Happy to answer anything.
