Lumi Math Planet: Explorer

Some apps teach math. This one sets out to make children love it. A universe your child lights up with their own mind Lumi Math Planet turns math into a warm, cinematic space adventure. Solve a puzzle and a dark little planet flickers to life — buildings rise, auroras bloom, and an adorable space friend floats down to say hello. From Glimmer Planet all the way to the Boss Planet, every right answer makes the universe a little more beautiful. No failure. No buzzer. No shame — only gentle encouragement. So confidence grows on its own. Polished down to the details Every planet has its own glowing personality. Every object has a warm, clay-style look. Every question is read aloud in a gentle, friendly voice. This isn't a worksheet with a cartoon stapled on top — it's a tiny world built with the kind of love you'd want a great teacher to have. Thinking, not just answers — contest-style puzzles Most math apps drill speed. Lumi builds minds. Our question styles are inspired by international early-math contests: number patterns, logic, spatial reasoning, simple combinatorics, real word-problems. Your child learns to think like a young mathematician, right at the kitchen table. So clear, a child plays before they can read Every single question is visual. Dice, ten-frames, number lines, growing rows, bar charts — abstract math becomes a picture you understand at a glance. No memorizing. No guessing. Just real number sense, discovered. From the very first number to contest-style thinking Addition & subtraction past 100 (with regrouping), multiplication, division, number bonds, place value, comparing, patterns, odd/even, ordinals, time and money — 40+ question types that level up automatically. Whether it's a pre-reader, a child just starting school, or anyone rebuilding their foundations, everyone begins right at their own level and climbs from there. Growth you can actually see The Parent Zone shows learning across five skill domains, spots weak areas, and opens one-tap focused practice. Export a worksheet and a learning report as printable PDFs, and carry every milestone with you. Four languages for questions and voice Questions and read-aloud are available in English, Traditional Chinese, Japanese and Korean. The app follows your device language, you can switch any time in Settings, and the menus are translated into many more languages. The quiet luxuries No ads. No data collected — progress stays on the device. No account, no login. Purchases and outside links sit behind a parent gate. What's free and what unlocks: the first planet, part of the daily challenge and two timed races are free to try. A single one-time in-app purchase unlocks every planet, the full daily challenge, unlimited timed races and practice for every question type. No subscription. Blast off — and watch your child build a universe that runs on what they just learned.
