“Can’t cancel — The app didn’t do what it said. Tried to have it track and stop from snoring. Didn’t do anything for snoring. The reason for 1 star is you can’t cancel the subscription. You can’t in Apple because it sends you to another…”

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.

Cancelling, in the store description
Does not say how to cancel
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.
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.
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.
Reported by users: Hard to cancel
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 (5.8% of 104 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Cannot cancel before trial ends — I have spent literal hours trying to find out how to cancel this trial. It does not show under subscriptions and doesn’t recognize my email address when I try to cancel that way. The app was a curiosity…”
“Impossible to cancel — If you sign up for the free trial anticipate paying for the full annual subscription. They make it impossible to cancel”
