“Nothing is free anymore — My favorite app is now FULLY behind a paywall subscription. You can search via barcode, not keywords anymore, but even doing barcode results in every useful information behind a paywall. Bro, I’m sick of this…”

What we measured

Themes reported by reviewers
1 theme 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
90% or more 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.
One source only — shown, not confirmed 1
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.

The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.
What we saw: Paywall blocks the basics: raised by 24 distinct reviewers (4.8% of 503 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“User-driven database, but you pay — Was free, now they make you pay to use/search items. Why contribute when you have to pay? Makes no sense to have to pay for access to a database whose majority of items’ ratings are user-driven. Will be…”
“Premium subscription sux — I paid for the "premium" subscription with "unlimited scans" but many products are locked behind the higher tier pay wall. The limited capabilities of the "premium" tier don't justify its cost and the app is…”
