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 1.55.1 of the app, analyzed 2026-10-05 . The app may have changed since.
The store currently lists version 1.55.1, updated 2026-09-25.
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 32 distinct reviewers — 4.7% of the 684 reviews scanned on this store leg (App Store).
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.
From the store listing: Usable without an account
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 (6 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.
Reported by users: Trial converts to a charge
The free trial demands a payment method up front and/or rolls into a paid subscription with no usable warning.
What we saw: Trial converts to a charge: raised by 5 distinct reviewers (0.7% of 684 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 5 distinct reviewers (0.7% of 684 reviews scanned)
Reported by users: Paywall blocks the basics
The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.
What we saw: Paywall blocks the basics: raised by 5 distinct reviewers (0.7% of 684 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“The game — I can’t even play the game cause of all the ads won’t even load up a game With out an ad”
“Meh — Fun but the ads make it genuinely unbearable, i understand having ads but when they are on every other level it just makes me close the app, im sure they do this to get you to buy the ads free version but id rather just download an…”
