Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
New: CDL words, explained. Tap an underlined term in any question to see what it means in plain English, with an example and a Listen button. Browse every term A–Z in the new Glossary. Also new on the home screen: CDL schools in your state, with a link to the full directory. Plus bug fixes and stability improvements.
Appworthy
cdl-helpWhat 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.
