A schedule can be ongoing and for specific days of the week, and specific times of those days. A schedule can also be for a specific date-range and times as well as location based (when you are within x metres of a particular place).
A schedule has two profiles, one for when the screen is turned on, and one for when the screen is turned off. The profiles control the Wi-Fi & Data states, brightness and screen time-out, and volume settings.
A schedule can also be given a name for easy identification.
In the paid version there is no limit to the number of schedules that you can set up. The free version is limited to three schedules.
