I have used this app several times, have not finished all the questions, however I have noticed some flaws:1. Glitches: A. The app sometimes after I answer a question & go back after I have finished the quiz my answer has changed which is frustrating because a large selling point for me was the ability of the app to summarize my strengths & weakness by percentage & rankings---which if my answers are reported incorrectly is uselessB. The app sometimes when I try to go back & forth, log-in & log-out, normal actions while "reviewing-on-the-go" & when I am going over questions in the "patient profiles" section, the profile for which I am answering the question on doesn't change with the new question---so I don't have the correct profile with the current question (irritating)C Lastly, the questions repeat themselves after going-in & out of the appSummary: It is very "glitch-y".2. Content: A. Some of the drugs I have never heard of before---which is very likely bc there are millions of them, but the authors, in my opinion should focus more on the "Top 200 Drugs" (Brand and Generic Lists) before introducing drugs that aren't available in Lexicomp or Epocrates, since, in my opinion student will download & PAY for this application to study for the NAPLEXB. Suggestion: Bring a pharmacist, former NAPLEX question writer or someone from the field of pharmacy to help with your question structures & drug selectionsAfter all of that, some good points: 1. About 65 to 75% of the questions are okay/good/challenging.2. The app does dig up some "forgotten", i.e. 1st-year, information3. It also give a ton of practice at K-type questions, so helps you get familiar & comfortable with that question structure.
