Findings and evidence

1 published · 1 shown, not confirmed

Context 1

Facts that add context without being a charge.

Cheapest and priciest options are far apart

Measured

In-app purchases run from USD 0.49 to USD 14.99 — a 31x spread across 8 items

Sources
The store listing
Agreement
A measured fact from one deterministic, checkable source.
Where measured
From the App Store listing
Definition

The disclosed in-app purchases span an unusually wide price range. Published as context: the cheapest and priciest items may be different kinds of product entirely, so the spread alone deducts nothing.

Open evidence

One source only — shown, not confirmed 1

Open observations that have not cleared the evidence bar.

Aggressive ad load

One source only

Aggressive ad load: raised by 11 distinct reviewers (about 1 in 9 reviews we read)

User reviews
Agreement
Only one kind of source so far. Shown, not counted.
Where measured
From App Store reviews

This observation has not cleared the required evidence standard.

Definition

Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.

Nothing was published as a thing to watch for in this assessment. That is not a finding that nothing is wrong with the app.

Aggressive ad load

Shown, not confirmed

Ugh!! TOO MANY ADS!! — This could have been one of the best trivia games in the entire App Store. Unfortunately the STRESSFUL & TIME-CONSUMING ADS made it unbearable! The game was relaxing but the ads were frustrating—too many and they…

1★ · App Store · 2025-12-12

Fun — Too many ads. I don’t want to pay.

4★ · App Store · 2025-12-09

Great but… — As you get higher and higher in the levels the ads are more frequent. Three ads in 10 questions is ridiculous, and you have to click off multiple screens to get out of the ad. Great way to spoil the continuation of the game…

2★ · App Store · 2025-09-18

A sampled review illustrates one person’s experience. It does not establish a finding on its own.

Measurements

5 measured · 3 not assessed

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

Five-star share of ratings

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app 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, not a finding.

Method and limits

What this report can and cannot show

How the automated analysis works

This assessment is produced automatically. Three independent signals are read — user reviews, 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.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A hands-on test can confirm or contradict a finding and adds its own measurements; it does not change a measurement row. Hands-on inspections are not yet open.
