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.
Which version this describes
When we ran this analysis, and what the store lists now.
This analysis describes version 1.2.37 of the app (the version number recorded inside the package we inspected), analyzed 2026-10-04 . The app may have changed since.
The store currently lists version 1.2.38, updated 2026-09-20.
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
1 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
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
From the package we downloaded and read — version 1.2.37, scanned 2026-10-01.
Permissions Android classifies as dangerous
1–2 requested
Counted against the eighteen permissions listed in collect-package.ts. A dangerous permission is one Android asks the user to grant; requesting one is not itself a finding.
Analytics or tracking SDKs in the scanned package
1–2 found
Advertising SDKs in the scanned package
10 or more found
Counted as distinct SDKs in the package we scanned. One mediation bundle can contribute several, so this is not a count of advertisers.
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 2
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.
Multiple ad networks bundled
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.
What we saw: Bundles 16 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, BidMachine, Chartboost and 12 more
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 42 distinct reviewers — 8.2% of the 515 reviews scanned on this store leg (Google Play).
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
Developer says data deletion can be requested
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.
What we saw: The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text
One source only — shown, not confirmed 1
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.
In the app's own text: Hard to cancel
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
What we saw: Sells a subscription in-app but ships no cancel or manage-subscription text of its own, leaving the store's settings as the only exit
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“UPDATE Aug 19: Since the Aug 3 update, several of the ads never 'time out'...you're stuck looking at them forever, without a way to get back to the game without closing the app completely. Enjoyable but SO many ads! My favourite is when…”
“I love coloring the pictures but I absolutely DESPISE the extremely high number of mandatory ads with no way to bypass. I tried the so- called "no ad" version of the game, but this did not skip ads- it simply made viewing time shorter…”
