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

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.
Positive evidence 1
Things this app does right, published at the same strengths as the catch list.
Developer says data deletion can be requested
The developer's data-safety disclosure on the store states that users can request deletion of their data, or the app's own text offers a way to delete the account. This restates what the developer declares; it is not a test of whether deletion works. Apple publishes no equivalent disclosure, so on an Apple-only listing only the app's own text can support it.
What we saw: The developer's store data-safety disclosure states that data deletion can be requested; we have not seen a deletion control in the app's own text
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: Aggressive ad load
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 8 distinct reviewers (2.0% of 405 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“I'm sat in totally flat calm, Nautide shows a 30 kt gale and a blizzard ( in August!). Pop up ad is for a crypto scam site. Completely unreliable and dodgy links.”
“Good app, but far too many ads just to see forecasts even if it's tomorrow's forecast. I get it, ya gotta make money. Just tone the ads down a bit and this app would be solid.”
