QuizBot — An Android App That Turns Screen Time Into Learning Time

I built an Android app that blocks websites on the kid's device — but instead of a plain "access denied" page, the child has to win 3 cognitive mini-games first. After winning, they earn 20 minutes of browsing time. It's parental control, but with a positive twist: learning always happens before screen time.📦 Download on Google Play: https://play.google.com/store/apps/details?id=com.quizbot.android.blocker🌐 Website: https://quizbot.win
The Problem I Wanted to Solve
Most parental control apps on the market are negative by design. They block, restrict, and frustrate. The kid just sees a wall and gets angry. Parents end up as the "bad guys" every single day.I wanted to build something different: a system where the kid is motivated to learn, because learning is the direct path to the thing they want (screen time). No punishment, no negotiation — just a clear rule:
Want 20 minutes of YouTube? Solve 3 quick games first.
How QuizBot Works

1. Parent sets up blocked sites in the dashboard (or uses the Chrome extension on desktop).2. Kid tries to open a blocked site on their device.3. Instead of an instant block, the QuizBot screen appears: 📸 [SCREENSHOT 1: QuizBot blocking/lock screen]

1. Kid plays 3 mini-games in sequence:

📸 [SCREENSHOT 24: Puzzle game]

1. All 3 games completed → kid earns 20 minutes of browsing time on that site (or across all blocked sites, depending on parent config).6. The 20-minute credit expires in 24 hours if unused — so it encourages kids to come back and earn more.

Tired of being the "screen police"? The QuizBot Chrome Extension turns website blocking into a positive experience for your kids.Here's how it works:

They play a quick cognitive mini-game (Memory Cards, Logic Matrix, or Word Puzzles)
Win → they earn 20 minutes of browsing time on that site
Time expires in 24 hours if unused
The extension is part of the QuizBot ecosystem: a web app, Android app, and browser extension all working together. Your child can earn learning minutes on the phone and spend them on the desktop (and vice versa).
