Independent evidence report
The evidence behind this assessment
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
Which version this describes
When we ran this analysis, and what the store lists now.
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 we measured
Each line is a measurement published as a measurement, never a verdict.
Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

Themes reported by reviewers
1 theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
90% or more five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the 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 about the app, not a finding about it.
Graded bands · predicate set 1.4 · how these are measured
What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
Context 1
Measured and published because a reader would want to know — deliberately not a charge. The measurement alone does not show a harm.
Cheapest and priciest options are far apart
The disclosed in-app purchases span an unusually wide price range. Published as context: the cheapest and priciest items may be different kinds of product entirely, so the spread alone deducts nothing.
What we saw: In-app purchases run from USD 0.99 to USD 49.99 — a 50x spread across 10 items
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.
Reported by users: Users describe the free version as usable
Reviewers repeatedly say the free version is worth using on its own. Nothing we can measure corroborates that — a free listing with in-app purchases looks identical whether the free tier is generous or a demo — so this is published as what reviewers say, not as a measured credit.
What we saw: Reviewers describe the free version as usable: raised by 5 distinct reviewers (0.9% of 529 reviews scanned)
Reported by users: Paywall blocks the basics
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 (1.1% of 529 reviews scanned)
Highlighted reviews
Representative public review excerpts shown as user reports, not Appworthy audit evidence.
“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…”
