Paywall blocks the basics

Shown, not confirmed

Good, but… — This is overall good but almost all the features are locked behind a paywall but that’s fine because it’s a one time purchase so it’s not a supscription

Shame — They locked it behind a Paywall but it’s good app

5★ · App Store · 2026-09-17

Alright for free — The free version is ok, I like it, but I just can’t do a lot with it. Stop motion studio is just pretty much advertising the pro version the whole time

😍 — Get it you have to get this app if you are into animated videos and need somewhere to start to get this the membership is worth it. It’s a one time purchase. I am 100%. I love this. I’ve made so many movies and I love sharing them…

5★ · App Store · 2026-08-29

Best stop motion app ever!!!!! — My friend said it was the best app for stop motion and he was right! Pay the $6.00 dollars for the upgrade, it is a one time purchase and it is so worth it! You will get the green screen ability, theme…

A sampled review illustrates one person’s experience. It does not establish a finding on its own.

Measurements

5 measured · 3 not assessed

“Not assessed” means we could not measure it. It is never a zero and never a pass.

Method and limits

What this report can and cannot show

How the automated analysis works

This assessment is produced automatically. Two independent signals are read — user reviews and the store listing — 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 It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an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.
