Blast off into a friendly galaxy where every problem solved flies your rocket a little farther. Cosmic Cadets is a gentle, ad-free space adventure that helps kids ages 5–8 build real math confidence — counting, adding, subtracting and more — one short, joyful mission at a time. No ads. No in-app purchases. No accounts. No tracking. Just the fun of getting it right. THE ADVENTURE • Journey across a star map of 15 hand-crafted levels • Each level is a quick mission of bite-sized problems • Solve them to fly your rocket across the screen and earn up to 3 stars • Friendly retries — a wrong answer never scolds; your cadet just tries again WHAT KIDS PRACTICE • Counting and number recognition • Addition and subtraction • Finding the missing number • More or less (comparing numbers) • First steps in multiplication (groups of 2, 5 and 10) Younger cadets count colorful space objects; older cadets work with the numbers themselves. GROWS WITH YOUR CHILD • Difficulty quietly adapts to each child, one skill at a time • Answer with ease and the numbers grow; find it tricky and it gently eases back • So the very same game fits a brand-new counter and a confident little adder COLLECT AND EXPLORE • Earn stars to unlock rocket ships and cute alien companions • A collection to come back to — with no coins to buy, ever • Set up several kid profiles on one device, each with its own progress FOR GROWN-UPS • A math-gated Parent Zone shows exactly which skills your child is mastering • Turn the sound effects and gentle background music on or off • Absolutely no ads, no purchases, no sign-ups — and nothing ever leaves the device PRIVACY YOU CAN TRUST • No accounts. No sign-ups. • No analytics. No ads. No tracking. • Everything stays on your child's device. • Delete the app and it all goes with it.
