Screenwise: Unlock screen-time with math

What it does

Screenwise locks your child’s device until they solve multiplication questions to earn screen time. They master times tables naturally, without arguments or stress. It feels like a game, but they’re learning without even noticing. Each correct answer earns 1 to 5 minutes. Wrong answers subtract 1 minute. The more they learn the more they can play. I built it for my son. Now he’s fluent in 1 to 12 times tables and earns his 2 hour daily limit in minutes. Next step: harder levels and algebra.
