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 4

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.

The free trial demands a payment method up front and/or rolls into a paid subscription with no usable warning.

Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
What we saw: Hard to cancel: raised by 13 distinct reviewers (3.1% of 414 reviews scanned)
Reported by users: Reports that the ads misrepresent the app
One source onlyShown, not confirmed — the only source is user reviews.view 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: Misleading advertising: raised by 6 distinct reviewers (1.4% of 414 reviews scanned)
Reported by users: Reports of unexpected charges
One source onlyShown, not confirmed — the only source is user reviews.view 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: Surprise charges: raised by 21 distinct reviewers (5.1% of 414 reviews scanned)

What reviewers said

Verbatim excerpts from public store reviews, shown as corroborating user reports. They are not Appworthy audit evidence, and a quotation is not proof of the finding it sits under.

Trial converts to a charge

I was offered a free trial, and was charged $14.99. Since I already paid for this month, there's been multiple times when trying to log on, there's a problem and it won't load. Or if it does finally load, it takes a very, very long time…

Requires $15 a month subscription. Even the 7 day free trial is asking for credit card information before it lets you try anything at all.

The app looks cheerful and colorful, with an attractive interface for kids, maybe even too colorful, as it can overstimulate them. However, I do not recommend it because of the trial issue. Be very careful, after the trial period ended, I…

Hard to cancel

This app is cute but not really what I was looking for. To everyone that is having trouble canceling the subscription, I guess there are two different ways to purchase the app and cancel. I tried to cancel through the website, and it said…

The app was anazing until I got a new phone as it wouldn't allow me to log in on my new phone for some reason, and I was charged. I tried canceling, but it has been a nightmare. You simply can't just call customer care to resolve your…

Don't even try the free trial. It was a little difficult for my daughter still but cute app. When you try to cancel it, when I click "your membership", every device says "error loading content", very convenient. When I click on "contact…

Reports that the ads misrepresent the app

I shouldn't have to pay for a subscription. I think this app should be free. Once I fill out my information it wants me to pay for a subscription. I feel like this app is false advertisement since all the advertisements I've seen never…

awful experience! I do not recommend this app. I wanted to try this app for my son, I accepted the 3month plan which was on offer (I screenshot the offer) which is £13.50 instead of £44.99 which i though was great. once I downloaded a d…

False advertising and useless customer service. My 2 year old is nonverbal but very good at the few games we have access to however he has become very bored with these games and even after talking to their "customer service" it's worse…

Reports of unexpected charges

Thank you for providing a much needed ph service to a population at a price. I find that products such as this are designed toward lower income communities, so its a plain slap in the face to continue to charge those populations for your…

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.
