Locks entertainment apps behind short, class-level quizzes and textbook-derived flashcards to make device use conditional on learning. The app, from IBES Nova Studio, blends photo-based quiz creation, a weekly study planner, and progress analytics into a parental control workflow. Parents set passing scores and earned screen minutes, while children unlock games after meeting study checkpoints. It fits parents and guardians who want to replace screen-time conflicts with measurable study routines tied to school materials.

Transforms passive screen time into measurable learning

Parental Control - Lock Apps enforces an incentive model where access to specific entertainment or social apps is gated until children complete short quizzes. The app's Smart App Lock prevents target apps from opening until a configured passing score is reached, and parents can assign the exact amount of screen time rewarded per session. This design links play to study through explicit, quantifiable rules rather than a simple time limit.

Turns physical textbooks into digital study material via photos

The app converts photographed textbook pages into interactive study cards using photo recognition, creating flashcards, matching items, and fill-the-gap questions. Multiple learning formats are available, including flip cards and listen-along lessons, so the same page can produce varied practice types. Parents can also build custom quizzes from homework notes, which integrates real classroom material into the child's device routine.

Fits daily routines with scheduling and progress feedback

The weekly study planner schedules topics and daily goals, while progress tracking offers detailed reports and a visual Mastery Map that highlights strengths and weak concepts. Parents see quiz results and total study time so they can adjust goals or passing thresholds. Quiet Hours can block app access entirely at set times, which helps enforce distraction-free family routines or bedtime without relying on quiz outcomes.

Requires permissions and exposes clear parental controls

The app runs on Android and requests app-usage and system overlay permissions to operate as an app locker. Those permissions are necessary for blocking and unlocking target apps and for converting on-device photos into quizzes. Parental controls include customizable passing scores and rule sets, giving parents direct control over the learning-to-play balance while making the permission footprint explicit in setup.

To sum up, a practical fit for parents focused on study-linked screen time

To sum up, the app is a sensible option for parents who want screen access to reward measurable study tasks rather than serve as an open distraction. It makes device time conditional and measurable, though it requires granting app-usage and overlay permissions during setup. For best results, use short, consistent study checkpoints aligned with school homework to keep the routine predictable and maintainable.
