The Time Block feature (Android only) allows parents to restrict the times in which a child can use their phone. When a child's phone is blocked they are only allowed to call 911 and the Emergency Numbers that parents have authorized. The parent can block the phone in half hour intervals for specific days of the week. Each individual half hour time period can be clicked to toggle between blocking and allowing use of the phone. Longer time periods can be toggled all at once by clicking and dragging over the desired time period.
