What is Lumi Math Planet: Explorer?

Lumi Math Planet: Explorer is an iOS app. Preschool Math Games Ages 3-6

Some apps teach math. This one makes a child 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.

Children ask to play it. That's the part that changes everything.

Crafted to a standard you can feel

Every planet is hand-painted. Every object is sculpted in warm, clay-style art. Every question is read aloud in a gentle, real 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-grade

Most math apps drill speed. Lumi builds minds. Our question styles are inspired by the world's great early-math challenges — WMI and Math Kangaroo among them: 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-grade thinking

Addition & subtraction past 100 (with regrouping), multiplication, division with remainders, 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 printable worksheet and a learning report (print it or save a PDF) and carry every milestone with you.

Four native languages

English · Chinese · Japanese · Korean — questions and voice fully localized, auto-matched to your device.

The quiet luxuries

No ads. Ever. No data collected — nothing ever leaves the device. No account, no login. Every outbound tap sits behind a parent gate.

One promise, kept: pay once, own it forever. No subscription, no nagging. Start free with your first planets and the daily challenge; unlock the whole galaxy whenever you're ready.

Blast off — and watch your child build a universe that runs on what they just learned.

(Question styles are inspired by international early-math contests for practice only; not affiliated with WMI, Math Kangaroo or any organization.)
