cobalt-weatherWhat 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.
