Short answer
A child who resists worksheets will often happily solve the same concepts wrapped in a game with progress and rewards. The key is engagement plus the right level: practice that adapts to what they find hard keeps it challenging without being discouraging. Lumi Math Planet wraps reasoning and competition-style math in a space-adventure, and its weakness tracker keeps the difficulty targeted so the child stays in the sweet spot. It's ad-free, collects no data from children, and is a one-time unlock — no pressure to buy more.
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. |
