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.

Store listing and review signals

What we measured

Each line is a measurement published as a measurement, never a verdict.

How these are measured

Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

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.
