For developers and the curious
The evidence, sources, measurements and versions behind every label above.
Open observations that have not cleared the evidence bar.
Paywall blocks the basics: raised by 6 distinct reviewers (about 1 in 83 reviews we read)
This observation has not cleared the required evidence standard.
The core of the app — not extras — sits behind payment, or previously-free function moved behind a paywall.
The store privacy disclosure (7 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.
This observation has not cleared the required evidence standard.
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.
Nothing was published as a thing to watch for in this assessment. That is not a finding that nothing is wrong with the app.
500 reviews read for this analysis. Each observation keeps the sample and store it was based on.
Locked previously free features behind paywall — NOT COOL.
Everything now behind a subscription paywall — — Nope! Byeeee…
Paid App Turning to Yearly Subscription — This was an app you had to purchase. It worked great. The app then recently switched to a subscription model, thus locking all the features behind a paywall. Very disappointing. Don’t waste your…
A sampled review illustrates one person’s experience. It does not establish a finding on its own.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
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.

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
Sync Solver now connects through Google Health. • Fitbit turns off its old connection on October 30. Sign in with Google once to keep syncing into Apple Health. Your purchase carries over. • Google is finishing its review of Sync Solver's new connection. As soon as it's done, the Google sign-in opens right in the app, with no update needed. • Syncs steps, distance, flights climbed, workouts, sleep stages, weight, body fat, resting heart rate, water and calories. • Fixes buttons that did nothing on iOS 18, Fitbit sign-ins that didn't finish, and workouts that stopped syncing. • Google Health syncing now also works on iPhones set to the Buddhist, Japanese or another non-Gregorian calendar. •…

fitbit-to-health-sync-solverAssessed 2026-10-27 from 500 user reviews, the store listing and its privacy label. We have not scanned the app's package, so nothing on this page was read from inside the app itself.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
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.
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.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
