Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the app package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Purchases the store lists
What this app sells
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.

These are really on sale; we just can’t tell from the name whether they recur.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.
Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
