Your child only wants to play on their phone or tablet? Make playtime something they earn. Learn2Play is not another app blocker. It's a parenting tool that turns screen time into a reward for learning. Instead of fighting over the phone every day, you create a simple system your child actually understands: finish a lesson, unlock your favorite app. No drama. No negotiations. Just a deal that works. When your child opens a restricted app, a friendly prompt redirects them to complete an educational activity first. Every finished lesson earns credits. Once they've earned enough, the apps they love unlock automatically. It's screen time they can feel proud of - and parenting that doesn't feel like policing. During setup, you decide exactly what gets restricted. Pick individual apps, entire categories like Games or Social Media, or both. Everything is protected behind a PIN, so your rules stay your rules. Learn2Play was built by parents who were tired of the same daily argument. We didn't want to take the phone away. We wanted to make the phone work for our kids, not against them. Try it. Your child might just surprise you. What Learn2Play really does Learn2Play helps you move from daily conflict to calm structure: Turns screen time into a motivating reward system Reduces arguments about homework and devices Builds independence and responsibility in children Supports a calmer, more respectful home environment Replaces constant control with clear, simple rules Terms of Use and Privacy Policy: https://general-laser.at/en/learn2play-terms-en The standard EULA from Apple is applicable: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
