Progress is gated behind watching an ad: "Watch ad to unlock"

Offers a one-time or lifetime purchase: "One time purchase"
The app's own text offers a one-time or lifetime purchase, or reviewers report that the price is stated clearly.

sha256:827bc8f0ed103f1653bbf652fd1f550266e1cf80cdcca6fbd9e98bf98674497dThe 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
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.
Open observations that have not cleared the evidence bar.
Paywall blocks the basics: raised by 12 distinct reviewers (2.7% of 447 reviews scanned)
This observation has not cleared the required evidence standard.
The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.
Deadline pressure in the app's own copy: "Learn even more new words with this exclusive limited-time offer"
This observation has not cleared the required evidence standard.
The app's own purchase copy attaches a deadline to buying — a countdown, 'offer ends in', 'limited time' — or ships a countdown view on a purchase-screen layout.

cool app. too many ads though
not impressed -- too many ads, not enough value
Ads ruin the experience. I'm fine with pop-up ads on my screen, but when I take a minute to swipe through a few vocabulary words, I should not be pulled away to watch an ad. and paying a monthly-yearly subscription to not have those…
Can't do much of anything on the app without paying for a subscription. Had me take a quiz to see my vocabulary level and when I finished, it paywalled me. I also noticed, when using the feature to pronounce the word displayed on the…
Locked behind a paywall after three days? No thanks. Not even worth the free trial.
take a wild guess what i dislike about this app? B-B-B-BINGOO basic features are behind a paywall. dont waste your time on this garbage and use a thesaurus (a book with synonyms (words that mean the same thing as other words) and antonyms…

vocabulary-google-com-hrd-vocabularyAssessed 2026-10-15 from 447 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.
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.
