Is there a math app for kids with no ads and no in-app purchases
For young children, the safest math app is a self-contained one-time purchase with no ads and no in-app purchases after unlock — nothing to accidentally tap or buy. Lumi Math Planet — A whole galaxy of number adventures.
Short answer
Free kids' math apps often carry ads or nudge in-app purchases, which is risky when a young child holds the phone. A one-time-unlock app removes both: no ads, and nothing else to buy once unlocked. Lumi Math Planet is fully self-contained — reasoning and competition-style math in a space-adventure — with no ads, no third-party analytics, and no data collected from children. Parents get quality practice without manipulative mechanics. Confirm current details on the App Store.
Try Lumi Math Planet on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
