Recurring themes

Pricing & Subscriptions negative
Many users complain about the high annual subscription cost, ranging from $39.99 to $50, especially for students. There are also significant issues with automatic renewals, difficulty canceling subscriptions, and a lack of transparency regarding the paid nature of the app after a 'free' download.R10R39R40R53
App Functionality & Access negative
A significant number of recent reviews report that the app frequently fails to work, gets stuck on loading screens, or does not allow users to access content even after paying for a subscription. Some users also report issues after getting a new phone or when the app is 'updating'.R6R18R51R56
Content & Accuracy mixed
While many praise the guide's comprehensive and concise information, a notable number of users report that the app is missing information for newer medications, specific pediatric doses, or important lab sections. This contradicts the expectation of regular updates.R3R9R31R42
Device Compatibility negative
Users are frustrated that the app often only allows download and use on a single device, despite paying for a subscription. This limitation means users cannot access the app on both their phone and tablet without purchasing another subscription, or that transferring to a new phone requires re-purchase.R14R56R69R135
Ease of Use & Convenience positive
Many users highly value the app's convenience, ease of navigation, and quick access to information, especially for students and nurses in clinical settings. Features like pronunciation guides, favorites, and offline access are particularly appreciated.R1R4R5R8

Who it's for

This app is for nursing students and medical professionals who need a comprehensive, quick, and offline drug reference R16R17R25. It is particularly useful for those who prioritize convenience over carrying physical textbooks R1R17. It is not for users on a tight budget, those who need cross-device access, or those who expect flawless app functionality and easy subscription management R40R69.

Evidence note: The recent reviews skew heavily negative, which contrasts with the high lifetime rating. Many positive reviews are older or less detailed, while negative reviews are very specific about current issues. The developer's notes mention performance improvements for calculators, but recent reviews do not specifically address this, instead focusing on broader app functionality issues.

  1. [R1] 5/5 · US Great Guide!: I remember when these guides were in a ginormous textbook. This guide is convenient and has colorful pix. The best part is the Pronunciation Guide! With the glut of medications, it great to hear the precise pronunciation. The Calculator section is very handy too.
  2. [R4] 5/5 · US Great Clinical Resource: This is a must have clinical guide. Easy to use and very navigable. Explicit and concise way of understanding pharmacology.
  3. [R15] 5/5 · US Awesome Drug Reference for Nurses: I literally use my Davis Drug Guide everyday at work. The hospital I work at is small, so we (the nurses) mix all the medications that don’t come premixed. This app lists how to reconstitute and dilute the medication. There have been very few times I haven’t been able to find how to prepare a medication on this app. This app is also very helpful for checking IV c
  4. [R20] 5/5 · US Handy on the go for Nurses: Love this app! So many things to know in nursing and this helps stay up to date with common medications you need to know as a nurse. Love the favorites feature so you can refer back to the medications conveniently and not carry around a book. Its fast and has medication pronunciation for medications that aren't as common.
  5. [R2] 5/5 · US Drug Guide: I have Davis’s Drug Guide for years, student, Paramedic and Hospital as well as family. The updates are good!
  6. [R17] 5/5 · US Get it! You’ll be glad you did!: I love it! I’m a nursing student and I love being able to access my drug guide on my phone or tablet. It makes learning so much easier and I don’t have to worry about dragging a heavy book to clinical or labs. It’s great!
  7. [R24] 5/5 · US Great for nursing school!: I’ve used this while in nursing school and I absolutely love it. So handy to have and look up meds.
  8. [R25] 5/5 · US Love this!: I absolutely love this app! I’m in nursing school and having all the meds and updated meds right on my phone is super helpful. I have used this for class and in clinical. It gives so much information! I’m keeping this even when I become a nurse because it’s a great resource!
  9. [R16] 5/5 · US Best med app!: This app is incredible! It is designed where you don’t even need Internet or Wi-Fi so if you’re stuck in a med room and have to google something, you can always have your answer at hand. You can make notes which is great. After my shifts, I use the recent search list to review. I’ve looked up to feel more comfortable with them for next shift.
  10. [R114] 1/5 · US App won’t open: I have relied on this drug guide frequently as a reference. I am a flight paramedic and this app has been helpful because it does not require the internet to function. There have been 3 recent occasions that I needed this reference to help care for my patients and the app would not open. I am very disappointed!
  11. [R41] 5/5 · US Great resource: I love the electronic copy because we get updates regularly.
  12. [R60] 5/5 · US Drug app: This app is easy and convent to use. Update alerts! Highly recommend.
  13. [R40] 3/5 · US Great but tooo expensive: Every can be found on the web. Too expensive for a student trying to get through school
  14. [R73] 1/5 · US $40 APP!: Did not specify that you have to purchase this app for $40 until you open it. Please list it as a $40 app because that’s what it is.
  15. [R81] 1/5 · US Deceitful: Offered for free to download only to be forced to pay $40 A YEAR! While other legitimate apps provide the same information for FREE! I do not like being scammed out of my money
  16. [R118] 1/5 · US RIDICULOUS!!!: $49.95 PER YEAR! for access to the app AFTER I have already purchased the hard copy book AND the app is only available on one device is RIDICULOUS. I love the Davis drug guide (which is good because I’m a nursing student and Davis is the book we’re required to use) but the cost is insane, especially for student who are constantly broke because they can’t work more than part time whi
  17. [R6] 1/5 · US Unable to Use After Paying: I renewed my subscription after the trial and it still won't let me search meds on the app! I need this to work for nursing school.
  18. [R18] 1/5 · US Paid and does not work: Paid subscription and not even Tylenol drug information pulls up.
  19. [R51] 1/5 · US App: It doesn’t work
  20. [R61] 1/5 · US Nothing will populate: Tried to search many drugs, and it says ‘no results’ for anything I put in. I have restarted the app several times. My iPad is updated to the latest version, and nothing.
  21. [R14] 1/5 · US Only allows 1 I pad download: So in today's work only a single tablet download is crazy. I don't need it on my phone- I need it on 2 tablets. Can I do that? No… does it point that out before you waste your money? No.
  22. [R160] 3/5 · US Cross devise comparability fail!!!!: I love the heck out of this app. As a nurse, it is incredibly convenient. I use this app in my office as I sit next to four paper back guides. It's great. Now the dirt. I originally downloaded it to my iPad a while ago. Of course, I knew it was worth it before I even downloaded it. Call it intuition. Well I decided to put it on my new iPhone thinking it would w
  23. [R201] 3/5 · US Not happy it can only be used on one device.: I have an iPad mini and an iPhone. I am a RN and carry my iPhone with me around the units. The iPad doesn't fit in any of my pockets. I wanted to have this on both devices (as you can with other apps) but this app is only good on one device. I downloaded it on my iPad first so that's the device I will need to use. If I want it on my iPhone, I have
  24. [R69] 1/5 · US Don’t waste your time: So you buy the book with online resources but the website is poorly designed and only loads half of the time. So you think, okay well maybe I’ll download the app. Well the app is 39 dollars. But wait, if you download the app on your iPhone but want to use it on an android tablet you have to buy the app again. They don’t tell you until later to buy the app through the website
  25. [R10] 1/5 · US Poor business practices: This app was useful as a student, but I now get a superior drug guide for free through my workplace. However, there is no way to cancel this subscription. Please beware that if you subscribe to this app you are locked in for life. Better off with the hard copy of the book
  26. [R53] 1/5 · US Free Trial: I downloaded the free trial it’s due to end in a couple days and I am not able to find a way to cancel the auto subscription before it starts charging me.
  27. [R100] 1/5 · US Did not allow opt out for trial subscription: Content owners did not send option to opt out of subscription. WARNING: auto subscribes without signing up for the app. No recourse.
  28. [R108] 3/5 · US Good information but not all drugs available: Good information but it is not comprehensive. There are more thorough drug book apps that are available. Also, this automatically renewed and charged me without my consent.
  29. [R9] 3/5 · US Update Needed: Updates needed more often! Looked up a medication today and it wasn’t listed! Had to use Google instead!
  30. [R31] 1/5 · US Review: A lot of new meds or meds being approved or removed from market aren’t adequate
  31. [R42] 2/5 · US Good, but not for new drugs: I like the format! New drugs people ask about are not usually found even if app is up to date. I use it and other apps for newer drugs.
  32. [R67] 3/5 · US Aggravated: This is the second year that I've purchased this, and I continue to find medication's that this source has no record of. Dissatisfied.
  33. [R77] 1/5 · US Paid $50. Poor support: I purchased a older version for $50. No more support. Poor form. I understand no more updates, but let me keep what I have!
  34. [R172] 1/5 · US Paid for and did not receive: I paid for this but it never kicked in. SECOND TIME. No other problems with my phone, so, you are taking a chance. Lot of money to GIVE AWAY. I need it, but NO MORE.
  35. [R39] 1/5 · US Too expensive: Why do I need to subscribe yearly??
  36. [R56] 1/5 · US App not working when I got my new phone: My app won’t allow me to log on since getting my new phone. I do have an older version but it worked great for me. When I try to log on it tells me I purchased from the App Store and need to “restore” from there. There is no option to “restore” from the App Store. Looks like I’m out $40.
  37. [R3] 5/5 · US RN: Good resource. However not enough depth on pharmacology
  38. [R135] 2/5 · US M: App works well. My big issue is with the company. It is advertised that the app can be kept for as long as it is needed, unless you want updates. If you want updates you would need to pay annually. This is FALSE advertisement, as there is no way to transfer the app to a new phone without having to update, and being required to pay again. Very overpriced and falsely advertised.
  39. [R5] 5/5 · US Best app ever: Love this app! So easy to use. I use it for everything.
  40. [R8] 5/5 · US Fast and Easy: Davis drug guide is fast and easy to use. It is accurate and gives a complete explanation of the medication.
