No review analysis published for this app.
“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.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
Version 3.0 is a complete update: a reworked calculator engine, a full-screen program editor, new worksheets (Inventory Turn Over, Return on Investment, Quadratic Equation, Spherical Triangle, Universal Constants and 16 probability distributions), new General Settings, new help documents for every menu, and many accuracy and stability fixes. Subscriptions are gone: after the 30-day free trial, a single one-time purchase unlocks the app for good.
Appworthy
rlm-12cxWhat 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.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
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.
