Appworthy
diamond-districtWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.

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.
