What’s the catch? Tracking and data collection concerns — 2 independent sources agree, backed by user reviews and the app manifest.

Analyzed automatically from 6 independent signals that had to agree — not a hands-on test, and not human-reviewed.

 Which version this describes

This analysis describes version 157.0 of the app (the version number recorded inside the package we inspected), analyzed 2026-10-06 . The app may have changed since.

The store currently lists version 157.0, updated 2026-10-05.

What the analysis found

Each finding shows what agreed and how strongly. Automated analysis

The catch list 1

Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.

Tracking and data collection concerns
2 independent sources agreefrom user reviews and the app manifestartefact 8eeb1088ad92…
The app ships session-recording or a wide tracking stack, holds permissions that read personal data, or is reported by users to sell, leak or over-collect it. The evidence line says which of those was observed.
What we saw: The app requests QUERY_ALL_PACKAGES, which lets the app enumerate every other app installed on the device.

One source only — shown, not confirmed 3

A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.

In the app's own text: Hard to cancel
One source onlyShown, not confirmed — the only source is the app's own on-screen text.artefact 8eeb1088ad92…
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
What we saw: 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
In the app's own text: Trial terms not stated in the app's own text
One source onlyShown, not confirmed — the only source is the app's own on-screen text.artefact 8eeb1088ad92…
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.
What we saw: Offers a free trial ("Try it free") with no renewal price, renewal date or auto-renew notice anywhere in the app's own text
Reported by users: Aggressive ad load
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 9 distinct reviewers (0.4% of 2444 reviews scanned)

What reviewers said

Verbatim excerpts from public store reviews, shown as corroborating user reports. They are not Appworthy audit evidence, and a quotation is not proof of the finding it sits under.

How the automated analysis works

Automated, corroborated, and never human-reviewed without a person.

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.

 Not yet human-reviewed

Several measurements above say “Not assessed” because no artefact we hold can answer them. A human review is what resolves those — and it can remove a favourable band as easily as add one.

Hands-on inspections are not yet open.
