Short answer
Many kids math apps review all content equally regardless of what a child already knows. Lumi Math Planet records results by question category across the entire app and surfaces the child's most frequently missed types in the Weak-Spot Practice mode — which generates new numbers for those same problem types, so the practice is genuinely different each session rather than memorizable. The Skill Tracking page displays a score across five domains (number sense, patterns, logic, space, real-life), giving parents a clear picture of which areas are strong and which need attention. This means practice time is spent where it matters most.
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. |
