What’s the catch? Multiple ad networks bundled — measured, backed by SDKs in the app package.

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 11.25.0-260714314 of the app (the version number recorded inside the package we inspected), analyzed 2026-10-04 . The app may have changed since.

The catch list 2

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.

Multiple ad networks bundled
Measuredfrom SDKs in the app packageartefact 82d512fb8f13…
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.
What we saw: Bundles 10 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, BidMachine, Fyber / Digital Turbine Exchange and 6 more
Reported by users: Aggressive ad load
Reported by 38 usersReported by users, not measured — nothing we can inspect could show this either wayview evidence
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Raised by 38 distinct reviewers — 7.1% of the 532 reviews scanned on this store leg (Google Play).

Context 1

Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.

Asks for more sensitive permissions than similar apps
MeasuredPublished as context — deliberately not a charge · from the app manifestartefact 82d512fb8f13…
The package requests substantially more of the device's sensitive permissions than the typical app in its category. This is a measurement, not an accusation: a permission is granted because a feature needs it, and a wide request list is a reason to look rather than a finding on its own.
What we saw: Requests 6 sensitive permissions (ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, CAMERA, READ_EXTERNAL_STORAGE, READ_MEDIA_IMAGES, RECORD_AUDIO); the median for 74 scanned apps in Music & Audio is 2

Positive evidence 1

Things this app does right, published at the same strengths as the catch list.

Developer says data deletion can be requested
Measuredfrom the store listingview evidence
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.
What we saw: 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

One source only — shown, not confirmed 4

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: A plan is pre-picked as 'recommended'
One source onlyShown, not confirmed — the only source is the app's own on-screen text.artefact 82d512fb8f13…
The purchase screen arrives with one plan already framed as the recommended or most popular choice, so the default is the app's preference rather than the user's. We do not compare the plans' prices, and only the app's own text evidences this, so it is shown, but never counted as a charge.
What we saw: Purchase screen steers the choice: "BEST VALUE"
In the app's own text: Pay to progress
One source onlyShown, not confirmed — the only source is the app's own on-screen text.artefact 82d512fb8f13…
Advancement or competition is gated behind spending money rather than playing.
What we saw: Progress itself is for sale: "Insufficient balance. Recharge to get more coins."
In the app's own text: Countdown-timer purchase pressure
One source onlyShown, not confirmed — the only source is the app's own on-screen text.artefact 82d512fb8f13…
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.
What we saw: Deadline pressure in the app's own copy: "Limited time offer"
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 82d512fb8f13…
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 ("Free Trial") with no renewal price, renewal date or auto-renew notice anywhere in the app's own text

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.

Aggressive ad load

The ads in this app are getting invasive. It inserts advertisements into podcasts, in the middle of sentences - these are definitely not the podcasts' ads. Unskippable ads appear while I'm navigating the app.

1★ · Google Play · 2026-07-28

Frequent unskippable full-screen ads triggered by general interaction with the app, not just before playing an episode. There's other apps. There's no need to tolerate this.

1★ · Google Play · 2026-06-27

This used to be the perfect app for my podcast needs. But lately it has become unbearable with ads. Full screen ads that come up while navigating, and are near impossible to close- long waits for the X to appear only for it to take you to…

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.
