Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
STEX drills keep your order on screen beside the grader lens, with Run again and a safe save to the matching form draft. Prep progress no longer slips backwards. Long form entries print in full. Practice exam review shows your answer and the correct one. Forms get a keyboard bar with Next and Done. Wider screens get a readable column. Corrected the doctrine reading list and the orders field card, and tightened confidence labels.
Appworthy
tbs-field-guideWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
No itemized purchase list is available for this listing.
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.
