“Worst email — This is the worst email app I’ve ever used. I’m using the free version and it has the potential to be a great app… but you can’t block emails unless you pay $10 + a month. That’s ok, I understand that. But you can’t block…”

Independent evidence report
Evidence and review signals

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
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: 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 (1.9% of 515 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“What’s going on? — I’ve been a long-time Spark user, I’ve recommended to anyone looking for a great email app. I’ve always understood introducing premium features to offset costs so putting things behind a paywall didn’t bother me as long…”
“Missing core functionality — No way to view only unread messages. Feel like that’s a pretty major oversight. This is not something that should be put behind a paywall, that’s just sleazy.”
