Short answer
Question types drawn from international math-competition styles (patterns, sequences, reasoning, spatial thinking) build genuine logic, inside a cinematic space-adventure. A weakness tracker targets exactly what the child keeps missing, so practice is efficient.
It's a pay-once kids' game, so there's no subscription and no ad-driven design.

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. |
