“Ads more Ads — I just downloaded this app for the first time in 10 years, and the amount of ads is absolutely ridiculous. When I used it years ago, I don’t remember seeing anything like this. Seriously…..what does Pokémon go have to do…”

Independent evidence report
The evidence behind this assessment
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.

What we measured
Each line is a measurement published as a measurement, never a verdict.
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.
Graded bands · predicate set 1.4 · how these are measured
What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
The catch list 1
Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.
Reported by users: Aggressive ad load
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Raised by 58 distinct reviewers — 11.6% of the 501 reviews scanned on this store leg (App Store).
One source only — shown, not confirmed 2
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: Tracking and data collection concerns
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 (1.0% of 501 reviews scanned)
Reported by users: Upgrade prompts use guilt-trip wording
Declining an upgrade is written as a loss ('No thanks, I don't want to improve'), or users report being repeatedly pushed to subscribe during normal use.
What we saw: Constant upsell pressure: raised by 19 distinct reviewers (3.8% of 501 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Too many adds and cannot view historical logs — This was a great app until a it became an advertisement; always seeking to gain money with subscriptions. And I cannot view old logs unless I pay for a subscription which was never an issue…”
“About the app — Too much ads and pop ups I have this app for 4-5 years and it seems they’re trying to push so many things and tracking so idk I’ll be changing elsewhere”
