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.
Which version this describes
When we ran this analysis, and what the store lists now.
This analysis describes version 1.3.5 of the app, analyzed 2026-10-04 . The app may have changed since.
The store currently lists version 1.3.5, updated 2026-09-08.
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
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
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.
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: Paywall blocks the basics
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 10 distinct reviewers (2.6% of 390 reviews scanned)
From the store listing: Usable without an account
The app's own screens offer a way past sign-up — guest access, skipping, or browsing before registering — rather than gating the product behind an account. The store's privacy disclosure is checked alongside it: that disclosure is self-reported, so it corroborates this credit rather than establishing it.
What we saw: The store privacy disclosure (2 entries) links no contact details or identifiers to the user — consistent with an app that does not require an account. Self-reported by the developer.
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“You have to pay to use anything — everything to use on here you have to pay do not recommended it unless your willing to pay like $50”
“I wish I could leave 0 stars — Honestly this is the worse app I’ve ever seen in my entire life. You cannot do anything without premium, and there are ads nonstop. This is honestly the worst app in creation.”
