QuizLock is your digital detox partner!
QuizLock is a screen time control app that helps you build healthy smartphone habits. After a set usage time, a quiz appears on your screen. Solve it correctly to keep using your phone โ€” or get locked out and take a real break.
Whether you're a parent worried about your child's screen time, a student trying to focus, or anyone looking to reduce phone addiction, QuizLock makes digital wellbeing fun and effective.
๐Ÿ”’ HOW DOES QUIZLOCK WORK?

Set your desired screen time limit (10 to 120 minutes)
Use your phone normally until the timer runs out
A quiz pops up โ€” solve it to continue
Wrong answer? Your phone locks automatically
Take a break, reset, and start fresh

It's that simple. No complicated settings, no intrusive permissions. QuizLock is a lightweight phone usage timer that works quietly in the background until it's time for your quiz.
๐Ÿงฉ KEY FEATURES
โฑ Screen Time Limit (10โ€“120 min)
Choose how long you want to use your phone before a quiz appears. Customize your usage time to match your daily routine. Start with longer intervals and gradually reduce for a step-by-step digital detox.
๐Ÿง  Age-Appropriate Quizzes (Ages 6+)
Quizzes are designed for all ages, from elementary school kids to adults. Questions cover math, general knowledge, and logical thinking โ€” so you learn something every time you take a break.
