[DEV] QuizLock - I built an app to locks

Hey everyone! I'm a solo developer from South Korea. I built QuizLock because I wanted a simpler way to manage screen time without the complexity of Family Link.

How it works:

Set a screen time limit (10-120 min)

When time's up, a quiz pops up (math, patterns, or emoji puzzles)

Solve it → keep using. Fail it → phone locks automatically.

Features:

3 quiz types, 3 difficulty levels (ages 6+)

Admin password so kids can't bypass it

7 languages supported

Free, lightweight, no battery drain

Play Store: https://play.google.com/store/apps/details?id=com.lockstar

Also just launched on Product Hunt today: https://www.producthunt.com/posts/quizlock

Would love to hear your feedback! What features would you want to see next?
