1. 5/5Incredible Content, Frequent App Crashes

   I am a PA student and find myself using the online version of the Merck Manual as my primary source of information to supplement my Clinical Medicine courses. The comprehensive yet concise information on nearly all diagnosis and treatment of disease contributes to the Merck Manuals status as the “Gold Standard” medical reference textbook. The fact that this wealth of knowledge is free to anyone with an internet connection is an invaluable gift to the world and something that should never go without praise. That all being said the App version is somewhat more primitive compared to the browser based manual, I like that it stores content locally for offline usage however it’s frequent App crashes become tiresome. Overall the Merck Manual is where my foundation of medical practice is based upon and I will be forever grateful and as a result I continue to recommend this IOS app and the browser version to anyone who listen.

2. 5/5A helping hand to calm during times of distress

   When I found I could get the Merck Pro on my phone I was thrilled. I have referred to the Merck Manual for years and now have it readily available to answer questions from family and friends is wonderful. Wit it being able to make updates quickly and having more information at my finger tips is great. I am a retired RN and the family turns to me when they are unsure of how to approach the doctor for a problem. I can help them understand the problem and what to ask the doctor. Thank you for being with me and my family.

3. 5/5Excellent Resource! Please add an auto-citation generator!

   As a student nurse, Merck Manual is my go to resource outside of what I am required to use for my classes. I often refer patients to the consumer version for further learning about disease processes. I find the visual layout more inviting to read and I really appreciate the added images & videos that are sometimes included. The information appears to also be up very to date. Only thing that is missing is an auto citation generator. That would be AWESOME!

4. 5/5Fantastic!!!!

   To have a resource as renowned & respected as the Merck Manual at my fingertips via this app; is tremendously reassuring. The quality of care I can provide is improved when someone presents with unusual / rare signs & symptoms and my mind &/or my body is tired and a decision I'm going to suggest for a patient lacks that good gut feeling,"... this is the right path." Of course, I still present my assessments to a superior... but, in the future, I will be that senior clinician. A resource such as this is precious, because it allows me to give my best to every person who presents to me for care. Even though our hours "on the wards" during the years of internship, residency & fellowship have improved (compared to what they were 10 years & earlier) YET the total hours are still quite long when you recall the time that must be dedicated in preparation for clinical seminars, going on Rounds with Attendings, and more. So there will always be tired physicians and surgeons in training, thanks again for this great resource of information.

5. 3/5Sends you back to homepage after 3 minutes of being dormant

   It’s an incredibly useful source for searching information on a variety of medical conditions/medications, but unfortunately the app will reset itself and take you back to the homepage if you exit the app and leave it dormant for even 2-3 minutes, rather than save your place within the app. From what I’ve seen, that’s a result of some iOS memory management “feature” that you can’t turn off or adjust in the app settings. Regardless of whose fault it is, the app will be of little use to providers if you cannot exit the app even for a minute or two before losing your place. I can’t bookmark every single condition I want to look up. This really need to be fixed.
