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
Reported by 47 usersReported by users, not measured — nothing we can inspect could show this either wayview evidence
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
Reported by 43 usersReported by users, not measured — nothing we can inspect could show this either wayview evidence
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
Reported by 35 usersReported by users, not measured — nothing we can inspect could show this either wayview evidence
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
Reported by 96 usersReported by users, not measured — nothing we can inspect could show this either wayview evidence
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
Measuredfrom the store listingview evidence
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
One source onlyShown, not confirmed — the only source is user reviews.view evidence
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
One source onlyShown, not confirmed — the only source is user reviews.view evidence
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
One source onlyShown, not confirmed — the only source is user reviews.view evidence
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)

Trial converts to a charge

SCAM ALERT. App offers a free trial, and guaranteed a reminder after 5 days, then when you proceed it charges you immediately. I will be contesting this charge with my credit card company YOU SCAMMERS

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…

Hard to cancel

What a deceptive company. Does NOT bill through Google Play. 15 buttons to cancel. F off with your purposefully difficult to cancel scam.

1★ · Google Play · 2026-09-29

Impossible to cancel. When you try to cancel, it just redirects you to a different site, which only has two options, which are update payment method or don't cancel.

Reports that the ads misrepresent the app

I'm shocked how bad this is. the ads are completely false advertising. opened once and never again, I feel pretty stupid having given them my money

The free trial period was a lie. The terms are stating that once the content was delivered after the subscription was paid - there will be no refund, no matter how few days has passed.

Aggressive ad load

too many ads, in the app and elsewhere. basic GPT distilled content.

Lovely app but too many ads, can't even open a book without ads. Not worth it

Tracking and data collection concerns

there is no free option. Just grabs your personal info so they can spam you and sell your info. then forces you into a subscription with a minimal free trial. nothing free here. only thing I learned was to avoid this app.

1★ · Google Play · 2026-09-27

Data harvesting app — These guys collect everything you do in their app and across your other apps and sell the data. Not worth it.

App bugs — Horrible app, horrible service! Just another way to sell your email info

Paywall blocks the basics

I really wanted this to be good and would have been willing to pay for it but the options to do so are out in the blue. Very expensive and the free version is so limited you can't really get an understanding about the app and the learning…

How the automated analysis works

Automated, corroborated, and never human-reviewed without a person.

This assessment is produced automatically. Three independent signals are read — user reviews, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.

No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.

There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.

Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.

 Not yet human-reviewed

Several measurements above say “Not assessed” because no artefact we hold can answer them. A human review is what resolves those — and it can remove a favourable band as easily as add one.

Hands-on inspections are not yet open.
