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
3 or more themes 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
90% or more 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.

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

Methodology

One source only — shown, not confirmed 4

A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.

Reported by users: Aggressive ad load
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 64 distinct reviewers (28.1% of 228 reviews scanned)
Reported by users: Reports that the ads misrepresent the app
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Reviewers repeatedly report that the app is not what its advertising showed. We never see the ad creative itself, so nothing we collect can corroborate or refute this — it is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Misleading advertising: raised by 10 distinct reviewers (4.4% of 228 reviews scanned)
Reported by users: Pay to progress
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Advancement or competition is gated behind spending money rather than playing.
What we saw: Pay to progress: raised by 6 distinct reviewers (2.6% of 228 reviews scanned)
From the store listing: Usable without an account
One source onlyShown, not confirmed — the only source is the store privacy disclosure.view evidence
The app's own screens offer a way past sign-up — guest access, skipping, or browsing before registering — rather than gating the product behind an account. The store's privacy disclosure is checked alongside it: that disclosure is self-reported, so it corroborates this credit rather than establishing it.
What we saw: The store privacy disclosure (4 entries) links no contact details or identifiers to the user — consistent with an app that does not require an account. Self-reported by the developer.

Aggressive ad load
“Too many ads! — Fun game, but the bombardment of ads ruins it. You have to watch ads in order to beat a level, then there are ads after you win. Not worth the battery drain.”

Aggressive ad load
“Fun but naturally unwinable — All the puzzles force you eventually to get stuck at a certain point and can’t win unless you pay or watch adds. There is no level that you can win with skill or puzzle solving and to proceed/complete a level…”
