Firstly a calendar can be very useful for knowing which activities kids are doing, what playdates etc. Schools sometimes throw one off things into the mix. Most parents would use a regular calendar anyway.
For JIRA - well that seems a bit heavy handed when trello would do but really it's a good idea. It's a todo list... so is the default todo app on your phone bad? Pen & paper bad? It's the same sort of thing.
As to your final paragraph, I'm wondering what effects using "productivity" tools like Trello have on a child's memory development. Do they remember chores better or worse independently? Do you remember typing a ticket as well as writing it down physically?
But if I find my self asking my kid “so... what went well?” or “I’m not sure that’s a 5 pointer” before they are working age I’ll book an appointment with a professional pronto!
oh god..
