Independent evidence report
Evidence and review signals
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 6.0.3 of the app, analyzed 2026-10-04 . The app may have changed since.
The store currently lists version 6.0.3, updated 2026-09-22.
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
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.
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: Aggressive ad load
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 58 distinct reviewers (15.8% of 366 reviews scanned)
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 (3 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.
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Limited use, too many ads — When I really needed this because my actual level was missing, I used it for a minute and I just got ads and “offer” to subscribe. I’m so sick of this model for EVERYTHING. The one time I did use it, I think it…”
“Functional, but unwelcome porno ads ruin it — Great tool, but I can do without the ads for adult oriented sites. Wanted to use this with my students, but the ads make it a non-starter.”
