Can the same school tablet follow a timetable through the day?
Yes. Skie schedules are windows with days, a start time, an end time and a list of allowed apps. The tablet switches between app sets by itself, for example school hours, break, study block and night mode, without anyone touching it. If windows overlap, the first matching one wins.
A school day is really several different devices in one. During a maths period you want the textbook app and a calculator. At break you may allow a wider list. After school, a study block might allow only learning apps, and at night most things are off. Skie does this with schedule windows attached to a group.
Each window has the days it runs on, a start and end time, and an app list. Windows can run overnight, so a night window that starts at 9 pm and ends at 6 am works as you would expect. Because the first matching window wins, you order them from the most specific to the most general.
The schedule is stored on the tablet, so it keeps working if the school Wi-Fi drops or the tablet goes home with no connection. The device clock is protected too: date and time are locked to automatic, so a student cannot change the time to escape a window.
Different groups can have different timetables. Class 6 and Class 11 do not need the same periods, and a hostel group can have an evening study block that a day-school group does not. Change a window once and it reaches the devices in seconds if they are online, or at the next sync if not.
A practical tip: do not try to mirror every period. Most schools do well with three or four windows, such as lesson time, break, study and night, and then use a manual lock or an extra app for the exceptions.
