UnlockSmart transforms the iPad unlock moment into a learning opportunity. Before accessing the iPad, kids answer a few quick, age-appropriate questions — earning minutes of screen time for every correct answer. Set up in seconds Parents configure everything in one onboarding screen: child's name, grade band, avatar, and a 4-digit parent PIN. Ready in under two minutes. Built-in grade levels Pre-K / Kindergarten (Ages 4–6): Counting, shapes, colors, phonics, and rhyming. Questions are read aloud automatically so early readers can play independently. Grades 1–2 (Ages 6–8): Addition, subtraction, early multiplication, spelling, and word problems — with voice read-aloud included. Grades 3–5 (Ages 8–11): Multi-step arithmetic, fractions, reading comprehension, figurative language, and inference. Earn minutes, not just answers Every correct answer earns iPad minutes. Parents control how many questions per unlock (1–10), how many minutes each correct answer is worth (1–15), and the daily screen-time cap. Repeated struggles are automatically flagged in the Parent Dashboard so you know exactly where to focus. Parent Dashboard Today's unlocks, accuracy, and minutes earned at a glance. Topic-by-topic accuracy bars for the last 7 days. A "Needs Attention" list of questions your child has missed 3 times. Daily and all-time streak tracking.
