This observation has not cleared the required evidence standard.

Definition

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.

Usable without an account

The store privacy disclosure (4 entries) links no contact details or identifiers to the user — consistent with an app that does not require an account. Self-reported by the developer.

Where measured
From the App Store privacy disclosure

This observation has not cleared the required evidence standard.

Definition

The app's own screens offer a way past sign-up — guest access, skipping, or browsing before registering — rather than gating the product behind an account. The store's privacy disclosure is checked alongside it: that disclosure is self-reported, so it corroborates this credit rather than establishing it.

Open evidence

Nothing was published as a thing to watch for in this assessment. That is not a finding that nothing is wrong with the app.

Reports that the ads misrepresent the app

Shown, not confirmed

Misleading advertising — This is a completely paid app masquerading as a free app. Nothing else to say about it, as everything is paywalled.

1★ · App Store · 2025-11-29

Annoying — Wasted 3-5 minutes on answering question and at the end requested to pay annual fee. It’s a bait and switch technique that I hate so much that I immediately deleted the app. Either ask for payment in advance or have a free…

1★ · App Store · 2024-09-02

Bait and switch — The app appears to be free or at least have a free tier. Instead, upon launching you are asked to answer a lot of questions, read a bunch of dialogs, configure notifications, etc only to discover that this is a paid app…

Upgrade prompts use guilt-trip wording

Shown, not confirmed

You have to buy everything — I used this app for a couple of days, and the first day it tracked but then it didn’t anymore and kept asking me to pay. I hate how I have to spend my money just to track my anxiety and stress which is…

Stress Gauge — This app has been the perfect stress gauge for me daily. It helps me to monitor my stress and work to manage it. When I’m reaching higher levels, I get notifications to get me to pay attention and help to manage my stress…

SCAM!!! — First off, you need a subscription to access the app. Yes, you need to pay $70 UP FRONT just to access the app. And on top of that, and what I find most concerning, you give all of your health data BEFORE it prompts you to pay…

Paywall blocks the basics

Shown, not confirmed

Payment required. Terrible. — I wanted to get this app just to find out you have to pay to do anything

1★ · App Store · 2026-10-10

Waste of money — There is a sneaky model, whole app is behind a paywall, and subscription is damn expensive. I forgot to cancel trial and now I have most useless and ugly app for a ton of money. Not recommend, mostly raw data, doubtful…

1★ · App Store · 2026-08-04

Not worth it — Everything is locked behind a paywall all the features it advertises aren’t available unless you pay a monthly subscription so completely not worth it save the space on your phone for literally anything else

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app 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, not a finding.

What this report can and cannot show

How the automated analysis works

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.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A hands-on test can confirm or contradict a finding and adds its own measurements; it does not change a measurement row. Hands-on inspections are not yet open.
