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.

Automated analysis in progress

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
3 or more themes 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 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.

Methodology

One source only — shown, not confirmed 5

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: Aggressive ad load
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 10 distinct reviewers (2.3% of 433 reviews scanned)
Reported by users: Trial converts to a charge
One source onlyShown, not confirmed — the only source is user reviews.view evidence
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 25 distinct reviewers (5.8% of 433 reviews scanned)
Reported by users: Hard to cancel
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
What we saw: Hard to cancel: raised by 21 distinct reviewers (4.8% of 433 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 6 distinct reviewers (1.4% of 433 reviews scanned)
Reported by users: Reports of unexpected charges
One source onlyShown, not confirmed — the only source is user reviews.view evidence
A large number of reviewers report being charged when they did not expect it — including being charged after cancelling during a free trial, or when a trial turned into a paid plan without warning. We cannot see anyone's billing, so this is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Surprise charges: raised by 28 distinct reviewers (6.5% of 433 reviews scanned)

Aggressive ad load
“Too many ads. — I cant even scan the code because it automatically just sends a link before me getting to scan the full image.”

Aggressive ad load
“Ads are ridiculous — The amount of ads on this app is ridiculous. I just downloaded it to try before deciding to pay for it but I cannot do anything without an ad popping up. I scanned a code and it was able to read it, but before I can…”

Aggressive ad load
“Free version unusable — Keeps taking images before I can center on the code. Then shows me full screen ads. I get it’s ad supported but come on. At least let me try the product!”
