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.

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.

Cancelling, in the store description

Themes reported by reviewers
1 theme 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
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.

What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
One source only — shown, not confirmed 1
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: Trial converts to a charge
The free trial demands a payment method up front and/or rolls into a paid subscription with no usable warning.
What we saw: Trial converts to a charge: raised by 6 distinct reviewers (1.2% of 512 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Scam — You knew exactly what you were doing in setting up prompts to buy. I tried to get out of the free trial prompt yet was charged for a full year. I want that money back now. You know what you’re doing, stealing. For a tuning app…”
“Paid app — Tired of all the subscriptions out there. I just wanted to use the trial and ended up getting charged after not canceling it fast enough. $7 a week is insane. Not worth it.”
