Lock n Learn

Lock n Learn is a parental-control app for the parent or guardian who sets up the phone.

You choose one entertainment app (YouTube Kids is suggested) and how long it may be used. Only time spent in that app counts. When the allowance runs out, Lock n Learn pauses it and shows a learning challenge. A correct answer, or a finished writing task, gives another period of use. A wrong answer gets a hint. The answer itself is never shown. You can also unlock with your parent PIN.

You pick the school year (Reception to Year 6), the subject (maths, English, science, writing, or a mix), and whether the session is a set number of questions, a timed practice, or a writing word goal. Questions follow England National Curriculum topics and are stored in the app. There is no internet service and no account.

Calls, emergency features, Settings, and every app you did not choose stay available. A persistent notification says protection is on. This is a family-trust tool: a determined person can still uninstall the app or turn the permissions off. It is not a device-admin lock.

Permissions, and why a parent is asked:
• Usage access — to see which app is in the foreground, not what is on screen.
• Display over other apps — to show the “Time to learn!” screen over the chosen app.
• Notifications — for the “protection is on” notice.
• Accessibility (optional) — only the package name of the app that comes to the front, so the pause can start a little sooner, plus a Home action. Lock n Learn works without it and is not an accessibility tool. The app asks for your agreement in its own screen before Android’s Accessibility settings open.

Nothing is sent off the device. There are no ads and no tracking.
