SkieCan two children share one phone or tablet?
It is built for one device per child. Skie links one child to one device, and blocks extra user accounts on it, so two children on one device would share the same rules. If one device must be handed on later, use the reassign flow in the dashboard instead of sharing.
The rules in Skie are attached to a child and a device together. Each child gets a profile, each profile gets one device, and the profile's apps, windows and location belong to that child.
Sharing one device runs against that. Skie blocks adding extra Android users and work profiles on a managed device, so there is no way to give each child their own login on the same hardware. Two children would see the same apps and the same schedule, and one child's location would be the other's.
If your children are far apart in age, that is the real difficulty. A ten year old and a fourteen year old rarely want the same apps or the same bedtime.
What to do instead depends on your situation. If you can, give each child a device, even a low-cost tablet for the younger one. If a device is passed from one child to the next, use reassign in the dashboard, which moves the device to the new child and clears the old child's data while keeping the device history.
For a family tablet that everyone uses, it is better managed as a single shared profile with a conservative list, accepting that it suits the youngest user.
See the family tablet entry for more on that case.
