The evidence, sources, measurements and versions behind every label above.
Findings that met the published evidence standard.

The app's own text says: "Finish playing to get rewards"
This observation has not cleared the required evidence standard.
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.

sha256:67bafba354cd29532e614f737ebbb98950ebd4037d757362ed22dedc395de597Ships a purchase screen ("Paywall intent is not provided.") with no dismiss, skip or "continue free" text anywhere in the package
This observation has not cleared the required evidence standard.
A paywall screen ships with no dismiss, skip or 'maybe later' affordance anywhere in the package, so the app's own text offers no way in without paying.

sha256:67bafba354cd29532e614f737ebbb98950ebd4037d757362ed22dedc395de597Sells a subscription in-app but ships no cancel or manage-subscription text of its own, leaving the store's settings as the only exit
This observation has not cleared the required evidence standard.
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.

sha256:67bafba354cd29532e614f737ebbb98950ebd4037d757362ed22dedc395de597Offers a trial ("Finish playing to get rewards") and states no renewal price, renewal date or auto-renew notice anywhere in the app's own text
This observation has not cleared the required evidence standard.
The app's own screens offer a free trial without stating, beside it, what happens when the trial ends. Read this as context rather than as a charge: renewal terms are normally shown on the store's purchase sheet instead, which we cannot see, and we can only observe one kind of evidence for this — so it is shown, but never counted as a charge.

sha256:67bafba354cd29532e614f737ebbb98950ebd4037d757362ed22dedc395de597The app's own text says: "Delete"
This observation has not cleared the required evidence standard.
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.

“Not assessed” means we could not measure it. It is never a zero and never a pass.

fast-pdf-reader-and-viewerAssessed 2026-10-24 from 176 user reviews, the app's package, the store listing and its privacy label.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
No itemized purchase list is available for this listing.
This assessment is produced automatically. Six independent signals are read — user reviews, SDKs in the app package, the app's own on-screen text, the app manifest, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
