Independent evidence report
The evidence behind this assessment
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.

What we measured
Each line is a measurement published as a measurement, never a verdict.
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
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 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.
Graded bands · predicate set 1.4 · how these are measured
What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
The catch list 1
Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.
Reported by users: Aggressive ad load
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Raised by 39 distinct reviewers — 7.7% of the 509 reviews scanned on this store leg (App Store).
One source only — shown, not confirmed 2
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: Progress pauses until you wait or pay
Use is rationed by an energy/hearts/lives meter that runs out and forces a wait or a purchase.
What we saw: Energy / timer gating: raised by 9 distinct reviewers (1.8% of 509 reviews scanned)
Reported by users: Reports that the ads misrepresent the app
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 6 distinct reviewers (1.2% of 509 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Too many ads — Love the game just too many ads.”
“Too many ads — Not going to watch 2-3 minutes of ads to play a level. Waaaay too long!”
