What we measured

Each line is a measurement published as a measurement, never a verdict.

How these are measured

Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the 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 about the app, not a finding about it.

What the analysis found

App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.

Methodology

Context 1

Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.

Cheapest and priciest options are far apart
MeasuredPublished as context — deliberately not a charge · from the store listingview evidence
The disclosed in-app purchases span an unusually wide price range. Published as context: the cheapest and priciest items may be different kinds of product entirely, so the spread alone deducts nothing.
What we saw: In-app purchases run from USD 4.99 to USD 99.99 — a 20x spread across 10 items
