About

Screen Patrol

Features
Read full description

Screen Patrol helps families manage kids' screen time with less arguing, less negotiating, and more clarity. Instead of hearing “just five more minutes” over and over, children get bones that represent screen time. Parents decide how many minutes one bone is worth and how many bones each child receives. Kids can clearly see how much time they have and choose when to use it. That is the heart of Screen Patrol: turning screen time from a daily conflict into a clear family agreement. How it works: • Children receive bones every day or every week • Parents choose how many minutes one bone gives • The child feeds the dog to start screen time • When time is up, the dog barks • Parents can add tasks for bonus bones For parents: Screen Patrol gives parents a simple way to set fair, clear rules without constant pressure. You can adjust settings for each child separately, choose how many bones they get, set the time value of each bone, use a PIN, and plan automatic refills. Bones can refill daily or weekly, depending on what works best for your family. For kids: Kids always know how much time they have. They do not need to guess, negotiate, or wait for someone else to decide for them. When they want screen time, they feed the dog a bone and use their own time. Screen Patrol does not block apps or lock devices. It is not a control tool. It is a tool for agreement, independence, and calmer family routines. Screen Patrol is for families who want clearer screen time rules, fewer daily conflicts, and a system children can actually understand.
