Division Sticker Book
Read full descriptionHide full description
Master division — including division with remainders — while collecting cute stickers! A learning app for ages 6–8. A new featured sticker each day keeps kids coming back. WHY I MADE THIS I went looking for a math app for my own kid, but they all locked you out halfway or charged a monthly fee. So I built the one I wanted: practice freely, no ads, no subscription. (It's the sequel to my times-tables app, "Times Tables Sticker Book.") PRACTICE THE BASICS, FREELY Work through each division set — in order, reversed, shuffled, and a check test. Plain division and division-with-remainders are mixed together, so kids build the key skill of telling "does it divide evenly, or is there a remainder?" Pass a test to earn a sticker. STRONG ON REMAINDERS Thoughtfully built around the tricky parts: the "remainder is smaller than the divisor" rule, and checking answers (divisor × quotient + remainder = dividend). SAFE AND SIMPLE - Practicing every division set is free - No ads, ever - No personal info collected, no account needed - Progress is saved only on your device WHAT KEEPS KIDS GOING - Pass a check test to grow a Crown — aim for the rainbow crown, a little every day - Master every division set to unlock Special Sea stickers - Missed one? Recovery lets you try it again on the spot FOR KIDS WHO WANT TO GO FURTHER (one-time purchase — not a subscription) The "Finishing Pack" unlocks three modes — mixed drills, time attack, and missing-number quizzes — plus every sticker book page and rarity. Family Sharing supported. Purchases require passing a parental gate. Proceeds from this pack help fund the next apps in the series. Let's turn division into "I can do it!" — start with the basics anytime.

Verdict
The clearest difference is ads: Division Sticker Book at none against 九九's shown. Division Sticker Book also leads on update cadence (every 4 days vs every 5 months). 九九's advantage is iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
