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
3 or more 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
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.
The catch list 4
Charges we publish at a strength we stand behind: measured from an artefact, agreed by independent sources, or reported by enough users to clear that charge's own published bar.
Reported by users: Hard to cancel
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
What we saw: Raised by 47 distinct reviewers — 3.8% of the 1,225 reviews scanned on this store leg (App Store).
Reported by users: Trial converts to a charge
The free trial demands a payment method up front and/or rolls into a paid subscription with no usable warning.
What we saw: Raised by 43 distinct reviewers — 3.5% of the 1,225 reviews scanned on this store leg (App Store).
Reported by users: Reports that the ads misrepresent the app
Reviewers repeatedly report that the app is not what its advertising showed. We never see the ad creative itself, so nothing we collect can corroborate or refute this — it is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Raised by 35 distinct reviewers — 2.9% of the 1,225 reviews scanned on this store leg (App Store).
Reported by users: Reports of unexpected charges
A large number of reviewers report being charged when they did not expect it — including being charged after cancelling during a free trial, or when a trial turned into a paid plan without warning. We cannot see anyone's billing, so this is published as an attributed user report: what reviewers say, and how many of them said it.
What we saw: Raised by 96 distinct reviewers — 7.8% of the 1,225 reviews scanned on this store leg (App Store).
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 3
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 15 distinct reviewers (1.0% of 1451 reviews scanned)
Reported by users: Tracking and data collection concerns
The app ships session-recording or a wide tracking stack, holds permissions that read personal data, or is reported by users to sell, leak or over-collect it. The evidence line says which of those was observed.
What we saw: Data & privacy concerns: raised by 5 distinct reviewers (0.4% of 1225 reviews scanned)
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 6 distinct reviewers (0.5% of 1225 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“They refused to refund the 1st charge because I forgot to cancel the free trial. it really bothers me when companies are rigid about not refunding the charge even when you let them know the same exact day of the charge (so it's clear you…”
“Interface isn't "exactly like" Instagram/TikTok, but it is very enjoyable. The main difference that hangs me up is how often I have to click a button instead of swiping to get to the next thing. Most importantly, I'm annoyed that if I…”
