It's a "parent portal" for an existing child care centre management service. It allows the guardians to manage their child's bookings, communicate with (and from) the CCC, pay their bills and other features; so it's not crazy fancy, but does use a large amount of React Native's features!
That is a great use case. I have used React for administration and management services at my office as well. Being able to get the app working across so many platforms so quickly is a huge selling point for the library.
