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.

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
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
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.

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 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.

From the store listing: Usable without an account
One source onlyShown, not confirmed — the only source is the store privacy disclosure.view evidence
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 (10 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.
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 6 distinct reviewers (3.8% of 159 reviews scanned)

Highlighted reviews

Representative public review excerpts shown as user reports, not Appworthy audit evidence.

Hard to cancel
“Virtually impossible to cancel — Data is questionable, based on Doctor input. There is no easy way to cancel your subscription!”

Hard to cancel
“No way to cancel premium subscription — I have followed the link to cancel my premium subscription. The instructions are to click “cancel” which would be great except there is no “cancel” to click.”

Hard to cancel
“Annoying and difficult to cancel — They do everything possible to keep you from canceling”
