Five-star share of ratings

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.

Version 2027.3.0 · 2026-10-23
**Built for iPhone Duo** CastKeeper now adapts to the foldable iPhone. Fold, unfold and rotate without losing your place: your tab, your episode and what's playing come with you. A new side rail keeps playback one tap away, and when the Duo is propped like a laptop, the player puts artwork above the fold and controls below it. **Queue and Knowledge, right in the player** Open your Queue or an episode's Knowledge notes without leaving what you're hearing. On iPad and an unfolded Duo they sit beside the player. Add a note at the exact moment you're listening, or create a Knowledge Kit in one tap. Nothing waits for your charger. **Know how long your Queue will take** The Queue now shows your…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

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 gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
