Themes reported by reviewers
2 themes 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
Under 65% 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.

App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.

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 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.

What we saw: Aggressive ad load: raised by 14 distinct reviewers (3.5% of 403 reviews scanned)
Reported by users: Hard to cancel
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.

Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“Useless. It's nothing but a diary filled with tons of ads. Use a notepad or something and make your own. Uninstalled.”
“Useless and too many adds and also ask for a 5star review again and again asking for premier also not good”
