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 2.8.10 of the app, analyzed 2026-10-05 . The app may have changed since.
The store currently lists version 2.8.10, updated 2026-10-01.
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
2 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: Reports of unexpected charges
A large number of reviewers report being charged when they did not expect it — including being charged after cancelling during a free trial, or when a trial turned into a paid plan without warning. We cannot see anyone's billing, so this is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Raised by 33 distinct reviewers — 5.4% of the 607 reviews scanned on this store leg (App Store).
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.
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 10 distinct reviewers (1.6% of 607 reviews scanned)
Highlighted reviews
