For developers and the curious
The evidence, sources, measurements and versions behind every label above.
Findings that met the published evidence standard.
Bundles 16 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, BidMachine, Chartboost and 12 more
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.

Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
Specific evidence of a useful property, within the stated scope.
The 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.
Sells 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.

sha256:026ee1ee0c4a5bc259c030c10ab1bdbce4552da1ee102faf4f7a3a755651cedcThe app's own text says: "Please press "Continue" if you choose to start using our app."
This observation has not cleared the required evidence standard.
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.

This observation has not cleared the required evidence standard.
The app's own copy describes working without a connection — offline mode, downloading for offline use, or content saved for later. Shown because readers filter on it; it is a feature, not a fairness property, and never counts for or against an app.

Trust me and ignore all the 5 star reviews. Too many ads. Like u get an ad just after playing 2 levels each. Game is really addictive, no doubt, but such a nice game all ruined by just ads. And the worst thing? You Can't even play with…
too many ads, and it felt like it was rushing me. I got really mad and couldn't play it. I still recommend trying it. but it is nothing like the ad. Again, do try it before thinking you hate it, but in my opinion, I wouldn't recommend it.
the game is kinda fun, but OH MY GOD, THE ADS, you get one basically after every single level, and not to mention that when you click on something like "customize your cafe," it resets your money and for some reason it reset my challenge…
A sampled review illustrates one person’s experience. It does not establish a finding on its own.
“Not assessed” means we could not measure it. It is never a zero and never a pass.

coffee-stackAssessed 2026-10-27 from 400 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.
