For developers and the curious
The evidence, sources, measurements and versions behind every label above.
Findings that met the published evidence standard.
Bundles 9 distinct ad networks / mediation SDKs: Amazon Publisher Services, AppLovin MAX, Fyber / Digital Turbine Exchange, Google Mobile Ads (AdMob / Ad Manager) and 5 more
The package embeds several distinct advertising or mediation SDKs — a stack built for ad volume, not for a single house ad.

sha256:6b41dafb8721be22c98e1051292b252bd5d0609ac7e896af7ae9f03aa29add6fAggressive ad load: raised by 15 distinct reviewers (about 1 in 27 reviews we read)
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.
The app's own text says: "* Subscription management is available on the ALTools website."
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.
Advancement or competition is gated behind spending money rather than playing.

This observation has not cleared the required evidence standard.
The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.

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.

I used to love this app but these days, I love it very less. It now shows a lot of advertisement thereby disrupting my songs. Also whenever it plays songs for some minutes, it will automatically stop. I'll have to go back to play it again…
Too many ads are popping up. I can't enjoy Alsong anymore.
I used to love this app, but recently they've been adding so many ads, it's just annoying. I hate having my music paused nearly every time I try to open the app. It's worse because all of these apps instantly install if you so much as tap…
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.

alsong-lyrics-mp3-karaokeAssessed 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.
