Independent evidence report
Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
Which version this describes

What we measured
Each line is a measurement published as a measurement, never a verdict.
Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.
Developer replies to reviews

Price in the store description
States no price and billing period
Cancelling, in the store description
Does not say how to cancel
Themes reported by reviewers
3 or more themes reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
From the package we downloaded and read — version 271.0, scanned 2026-10-06.
Permissions Android classifies as dangerous
1–2 requested
Counted against the eighteen permissions listed in collect-package.ts. A dangerous permission is one Android asks the user to grant; requesting one is not itself a finding.
Analytics or tracking SDKs in the scanned package
3 or more found
Advertising SDKs in the scanned package
None found
Counted as distinct SDKs in the package we scanned. One mediation bundle can contribute several, so this is not a count of advertisers.
Graded bands · predicate set 1.4 · how these are measured
What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
Developer says data deletion can be requested
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 5
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.
Reported by users: Aggressive ad load
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 14 distinct reviewers (2.3% of 607 reviews scanned)
In the app's own text: Hard to cancel
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
Reported by users: Paywall blocks the basics
The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.
What we saw: Paywall blocks the basics: raised by 12 distinct reviewers (2.0% of 607 reviews scanned)
Reported by users: Upgrade prompts use guilt-trip wording
Declining an upgrade is written as a loss ('No thanks, I don't want to improve'), or users report being repeatedly pushed to subscribe during normal use.
What we saw: Constant upsell pressure: raised by 6 distinct reviewers (1.0% of 607 reviews scanned)
In the app's own text: Countdown-timer purchase pressure
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"
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“having to wait five seconds after tracking for a premium ad is insane”
“would give 0 stars if i could. the ads are relentless. switching to a paper calendar once I copy down my data off this hellscape. don't offer a free option if you're going to shove ads down my throat every 2 clicks. 0/5”
