About this app

Are you tired of fighting over screen time? Do you wish your child would practice their math, reading, and IQ skills instead of endlessly scrolling?

Welcome to Smart Child Lock, the ultimate parental control and educational app lock that turns your child's smartphone addiction into a daily learning habit!

How it works: Instead of fighting your child to put the phone down, Smart Child Lock requires them to solve an educational challenge before they can unlock the screen. Want to watch YouTube or play a game? No problem—just solve this math equation or answer this IQ question first!

You set the rules, the time limit, and the difficulty. We handle the learning.

✨ Key Features Designed for Parents:

🧠 Educational Lock Screen: Forces your child to answer questions to unlock their device. We support Math (Addition, Subtraction, Multiplication, Division), Vocabulary, Pattern Matching, General Knowledge (GK), and even Translation questions!

⏱️ Smart Screen Time Limits: Set custom session timers. Allow your child 15, 30, or 60 minutes of uninterrupted screen time before the phone locks again and requires another educational puzzle to be solved.

👶 Adaptive Difficulty (Ages 3-10): Whether you have a toddler learning basic addition or a 10-year-old practicing multiplication and IQ logic, the app automatically adjusts the difficulty of the challenges to fit your child's age perfectly.

🔒 Unhackable Parent Protection: Kids are smart, but we are smarter! The app is secured with a 4-digit Parent PIN. You can also enable "Device Admin Protection" so your child cannot uninstall or delete the app without your secret PIN.

🛑 Complete App Control: You decide when the phone is locked. Put the device in Lock Mode when it’s time to study, eat dinner, or go to sleep.

Why choose Smart Child Lock? Unlike traditional parental control apps that simply block everything and make kids angry, Smart Child Lock is a "win-win". Your child still gets to play their favorite games or watch videos, but they have to earn it with their brain. It replaces mindless scrolling with productive, brain-stimulating study time.

Perfect for kids with ADHD, children struggling with math homework, or parents trying to establish healthy digital boundaries.
