Kinboard is here
The cork board I made for my own family is on the App Store.

It started with the printed calendar my fiancée hung in our kitchen, which I was terrible at keeping up with. So I made one I'd actually enjoy using.
Everyone's week goes on a cork board, with each person's plans in their own marker color. Type a plan the way you'd say it (like "Leo's haircut sat 10am") and it lands on the right day, or paste in the school newsletter and keep the dates you want.
The other parent joins with a one-time code, and both phones stay in sync. You can leave each other little notes on the board that look handwritten, which is my fiancée's favorite part.
