Screen time you earn — not screen time you fight over. QuizLok blocks the apps that eat your day and gives them back only after you pass a short, AI-generated quiz. Learn something, unlock something. It's that simple. HOW IT WORKS 1. Pick topics — math, science, history, or your own custom subjects. 2. Block apps — choose what stays locked until a quiz is passed. 3. Take a quiz — fresh AI questions every time, adapted to the right level. No memorizing answers. 4. Earn screen time — pass, and your apps unlock for the time that was set. FOR FAMILIES Stop being the bad guy. Set the rules once and let QuizLok enforce them. • Choose which apps are locked and how much time a passed quiz earns • Steer what your child studies • Weekly report cards show what they're actually learning • A bypass-proof setup with no easy off switch — nothing kids can quietly get around FOR YOU Not a parent? QuizLok works just as well on yourself. • Turn doomscrolling into study time • Prep for a cert or exam while you earn your break • Built for anyone who knows willpower runs out — future-you can't bargain with present-you WHY IT WORKS Willpower isn't the answer, and neither is another timer you'll just tap "ignore" on.
