KeyDo - Learn. Earn. Unlock. Turn screen time into learning time. Every parent knows the daily standoff: reminders, negotiations, timers, and "just one more minute." KeyDo changes the pattern. Instead of simply limiting device use, KeyDo turns your child's favorite apps into something they earn by answering short, fun learning challenges first. Less arguing. More learning. Better habits. And they're not alone. Key the Fox, your child's clever, encouraging learning buddy, cheers them on at every step, turning study time into a quest instead of a chore. How It Works Learn Kids complete quick, age-appropriate challenges matched to their grade and subject, with read-aloud, tap, drag, and spell activities that feel like a game. Earn Every correct answer earns XP. Answer in a row to build a streak and earn even more, connecting effort directly to reward. Unlock When the learning goal is met, kids trade their XP to unlock real screen time on approved apps, safely powered by Apple Screen Time. Why Families Love KeyDo - Earned screen time: reframes screen time from something kids demand into something they achieve. - Interactive challenges: math, reading & language, science, and brain-agility puzzles that keep kids engaged. - XP, streaks & leaderboard: playful motivation that makes kids want to come back and learn. - AI Homework Helper: snap a photo of any worksheet and get instant, teacher-style feedback. - Real parental controls: you choose which apps are locked and how they're unlocked, backed by Apple's own Screen Time. - Progress dashboard: track questions answered, accuracy, and growth at a glance, and adjust the curriculum any time. Designed for Parents Set it up once and let learning do the gatekeeping. From an easy dashboard, customize learning goals, pick restricted apps, monitor progress, and celebrate wins, all without the constant reminders. More Than Screen-Time Management KeyDo helps kids build habits that last well beyond academics: - Self-motivation - Responsibility - Critical thinking - Perseverance - Confidence By making learning the front door to screen time, KeyDo empowers kids to take ownership of their growth, and gives parents peace of mind that every minute has been earned.
