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.

Themes reported by reviewers

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.

Methodology

One source only — shown, not confirmed 3

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: Price keeps rising
One source onlyShown, not confirmed — the only source is user reviews.view evidence
The price of the paid tier has been raised on existing users.
What we saw: Price keeps rising: raised by 6 distinct reviewers (1.1% of 552 reviews scanned)
Reported by users: Reports that the ads misrepresent the app
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Reviewers repeatedly report that the app is not what its advertising showed. We never see the ad creative itself, so nothing we collect can corroborate or refute this — it is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Misleading advertising: raised by 5 distinct reviewers (0.9% of 552 reviews scanned)
Reported by users: Tracking and data collection concerns
One source onlyShown, not confirmed — the only source is user reviews.view evidence
The app ships session-recording or a wide tracking stack, holds permissions that read personal data, or is reported by users to sell, leak or over-collect it. The evidence line says which of those was observed.
What we saw: Data & privacy concerns: raised by 5 distinct reviewers (0.9% of 552 reviews scanned)

Price keeps rising
“Price increased from $8 to $13, really? No thanks. — This is enough of a bump in price for me to cancel and move to their competitor. I’ve liked their service but even at $8 a month I thought it was expensive. Increasing your price by 63%…”

“Saves being bothered spam — RoboKiller is quite creative and it’s responses to spam calls and blocking unnecessary callers saving me time and effort. They know when to let something important go through even if it’s not on your contact…”
