CLocked helps schools create focused, distraction-free classrooms without taking away the tools students actually need to learn. With a single QR scan, students "clock in" to class mode. While clocked in, only the apps your school or teacher approves stay available. When class ends, full access returns automatically. No manual setup. No confusing settings. WHY SCHOOLS CHOOSE CLOCKED - Built on Apple Screen Time. Restrictions are applied securely and on-device using Apple's own framework, not workarounds. - Teachers stay in control. Allowed apps are defined by class, period, or schedule. - Inclusive by design. IEP and 504 accommodations are fully supported, so students who need specific apps keep access at all times. - Phone calls always work. Students can reach emergency contacts even while clocked in. - Hands-off for students. Just scan and go. HOW IT WORKS 1. Your school provides a school code to get started. 2. Students scan a QR code in class to activate class mode. 3. Only approved apps are available while clocked in. 4. When the day ends or the student clocks out, normal use resumes. PRIVACY YOU CAN TRUST CLocked collects no data from this app. App rules apply only during school hours and only when a student clocks in. Your device is yours the rest of the time. Designed for grades 6 to 12 and higher education that want fewer distractions without blocking essential learning tools. CLocked requires a school code to use. Ask your school if CLocked is part of their program.
