Most parental control apps just block. SmartBlock makes kids earn access. Every time your child tries to open a blocked app YouTube, TikTok, Instagram, games they get a math problem. No solution, no access. Simple. HOW IT WORKS Set which apps get blocked SmartBlock intercepts each access attempt Child must solve a math problem to proceed Parents control difficulty and operations MATH LEVELS From simple addition to mixed operations you choose what fits your child's grade. Addition and Subtraction Multiplication and Division Adjustable difficulty (Easy to Hard) BUILT FOR PARENTS Native Screen Time and Family Controls integration No accounts required fully offline Zero ads, zero tracking Everything stays on your device (no servers) iPhone, iPad, and Mac (M1 or later) WHY PARENTS CHOOSE SMARTBLOCK "I don't want to just take away the iPad.
