The full report
The evidence, sources, measurements and versions behind every label above.
Findings and evidence
No findings are published for this listing. These are review signals, not findings: nothing here is an assessment.
No recurring theme reached our reporting threshold in the reviews we scanned.
What reviewers report
555 reviews scanned. These are signals from public reviews, not findings. Nothing here is an assessment.
No recurring theme reached our reporting threshold in the reviews we scanned. That does not establish that reviewers had no problems.
Measurements
“Not assessed” means we could not measure it. It is never a zero and never a pass.

Themes reported by reviewers
No 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
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the app 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, not a finding.

Method and limits
How a review signal works
A review signal is produced automatically from public app reviews by a classifier — never by a hands-on Appworthy test, and never by a human analyst. It exists so a real, not-yet-audited app can carry more than a blank “Not yet tested” listing, without ever being mistaken for an assessment.
A theme only appears above once at least 5 distinct reviews corroborate it — one angry review can never tag an app. These thresholds are published settings and may be tuned as coverage grows.
It carries no confirmed findings — reviews are one kind of evidence, and nothing here has been hands-on tested. The moment Appworthy publishes a full assessment of this app, it replaces this signal, permanently.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review replaces this review-derived signal with hands-on, recorded measurements. Hands-on inspections are not yet open.
