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

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.
Pay to progress: raised by 10 distinct reviewers (about 1 in 40 reviews we read)
This observation has not cleared the required evidence standard.
Advancement or competition is gated behind spending money rather than playing.
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.

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.

Pretty decent Survivors-like (or as the weirdos call it 'bullet heaven'). All ads are optional, but all bonuses require watching a looooong ad, sometimes 2, unless you pay money, or have gems or keys (chests only). What I appreciate most…
forced video ads for most things...and just basically copy/paste of any other similar style game. 99% of the 5* reviews are bots.
New updates makes you watch more ads for less items. Uninstalling.
difficulty scaling is immense, rewards are pitiful, 30 bucks to remove ads, ads will sometimes not register as watched for rewards, 2 slots for UNIQUE gear that you can't actually get, not even a weak starter. incredibly pay to win, has…
Pay to Win game. The aesthetic is good but difficulty scaling sucks. There is no real way to grind to get stronger. You cannot grind on lower levels as they do not drop chest keys nor upgrade items anymore. The latest event (Vlad) is a…
Pay To Win The gem economy is a joke. Earning 50 gems a day when chests cost 5,000 means you hit a massive paywall instantly. On top of the greedy monetization, the game isn't even optimized. It constantly chops and drops frames on my S23…
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.

undead-slayer-google-com-undeadslayer-atwo-epl-gp-oneAssessed 2026-10-31 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 recurring plan the store lists is named as weekly, the term read from the purchase names, with a list cut off at the store’s 10-item maximum not assessed; 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.
