What’s the catch? Nothing we could corroborate against this app.
Analyzed automatically from 3 independent signals that had to agree — not a hands-on test, and not human-reviewed.
This analysis describes version 4.0.0 of the app, analyzed 2026-10-06 . The app may have changed since.
The store currently lists version 4.0.0, updated 2026-09-28.
What the analysis found
Context 1
Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.
One source only — shown, not confirmed 2
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.
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.
Users describe the free version as usable
The best app — This is the best app I ever used I don’t need to pay anything that’s the best part. It’s so helpful with everything if something happens I always go in this app and it tells me everything I love this app it’s the best app…
This app is perfect. — When I opened this app I didn’t have to pay or anything. It helps me realize what my flow and cramps mean, when I had a headache it showed me reasons why and how to stop it. There is more like headaches, migraines…
I LOVE IT — This period tracker app is great especially for newer people! There are so many free features but there are a few things I wish yuu out didn’t have to pay for. Like gurl I’m already having my period week why make me pay for…
Paywall blocks the basics
Amazing. ALL FREE — I have looked at a few other trackers, but this one is so ridiculously easy to use! You don’t really need to pay for anything in order to get a full experience. You can get tips and data and log things and even…
Good, could be better — It’s great for what it’s supposed to be used for, but the extra features like tips on cramps and stuff are NOT free. Why should we have to pay for basic tips and features on the app for our period? Why should we…
Period tracker — This app is soo good you barely have to pay for anything you can read up on things like why you got your period and how! I LOVE IT
What this app sells
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.

These are really on sale; we just can’t tell from the name whether they recur.
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.
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.
