A calm, ad-free drawing and coloring book designed for children ages 3 to 7 — and for the parents who decide what's on their kid's iPad. WHAT MAKES IT DIFFERENT • No ads. Not in the app, not in the menus, not anywhere. • No subscription. One small one-time purchase unlocks every premium level forever, on every device signed into the same Apple ID. • No data tracking. We don't ask for an email, a sign-in, or your child's name. • No external links. Nothing your child can tap will take them out of the app. • Parental gate. Every purchase requires an adult to solve a two-digit math problem — your toddler cannot accidentally buy anything. WHAT'S INSIDE • 10 themed coloring worlds — animals, nature, fantasy, space, ocean, vehicles, food, dinosaurs and more • 3 worlds free forever, including a blank-canvas Free Drawing mode • Gentle phonics mode — tap the picture, hear "D is for Dog" • 24-color palette with adjustable brush sizes, fill bucket, eraser, and a small set of friendly stickers (no in-app currency, no loot, no rewards pressure) • Save drawings to a built-in gallery and share them as PNG • Available in English, Spanish, French, German, Japanese, Korean, Chinese (Simplified), and Chinese (Traditional) ONE-TIME PURCHASE The only paid feature is "Unlock All Levels" — a single non-consumable purchase that opens the 7 premium worlds permanently. Restore Purchases is available on the paywall and in Settings; switching devices keeps your purchase. DESIGNED FOR FAMILIES Built to meet Apple's Kids Category guidelines: no behavioral advertising, no third-party analytics, no external links, parental gate on payments. If something doesn't work the way you'd expect, write to us — a real person answers.
