Update: fixed!! (App now freezes when searching)

I have been using the app for several years now, and have been loving the app. I have recommended to numerous colleagues and residents I teach. However, the app now seems to hang when using the search function. I believe this has been happening since the most recent update, perhaps last couple of weeks. The search function is honestly the most important function as you don’t have to look through the book like I would have to with a physical copy. So I stopped the subscription before it was time to renew. I’m considering buying the web edition even though it’s more expensive. Hopefully search function doesn’t freeze the app on the web edition. And I hope I can use the web edition as a PWA on my phone. 🤞🏼Hopefully the developers will fix the bug soon!

Update: soon after the above review, the issue was fixed. The search function works as well as before. Thank you to the developers for listening!

UPDATE: Has the issue been resolved? If so, we'd appreciate it if you could update your review.
PREVIOUS: We're sorry to hear you are having issues with the search functionality in app. The issue you are experiencing is related to the iOS 17.2.1 release that came out in late Dec. We are working on an automated fix for the issue, and hope to have it out sometime next week. In the mean time, if you navigate to your accounts management screen in app. Then select Force Content Download -> Update Now; the problem should resolve itself after the content update. Please let us know if you need any further assistance by contacting our tech support team at or by phone at 540-987-9480 (9-5 US ET) and we will be happy to help.

I used to be a Clinical Laboratory scientist in my premed years and has worked in all the departments. But Microbiology/Infectious Disease, as everybody knows, needs constant research. What you knew 2 weeks ago will be outdated now. That’s why Sanford Guide never left my pocket (before the app age) and thank God it’s easier and faster access now with the app. I know it’s getting more expensive every time I need to renew but I always rely on Tax deduction—hopefully that doesn’t go away with today’s uncertainty. Thank you very much all you contributors for helping us help ALL people in need! Sanford Guide is consistent, concise, up-to-date (not a trademark), and very INDISPENSABLE!

Last update destroyed program

This was a great app until the last update. Despite paying the yearly fee, the program will not update. I cannot login with email and password. Even trying to reset password gives me an invalid email message. Company denies the issue and blames it on Apple and the user. Rather then help, they just suggested cancelling my subscription if I am not happy (after keeping the payment). This is very disappointing from a company that used to be highly regarded in the medical field, and one that I used as a physician for years.

Addendum: deleting the app and redownloading allows updating content, but any updates require this to be done, unlike every other Apple app. There is also a bug in the app that you cannot create an account despite a button to create account. It also will not link to an account you set up via the internet either. The company's response is that it must be my fault.

UPDATE: Has the issue been resolved? If so, we'd appreciate it if you could update your review. ORIGINAL: We’re sorry that you’re unhappy with our support. As stated in our correspondence, your subscription is through Apple, so no additional login is required to use the app or receive updates. Creating an account is only necessary for cloud backup and syncing with other devices via the Sanford Guide Cloud. Unfortunately, Apple will not allow us to access your account without action on your part, so we cannot associate your Apple subscription with a Sanford Guide Cloud account - only you can do that. Since you do not yet have a Sanford Guide Cloud account, we have created one for you, and will email you credentials to use. You can always go to the app’s Account screen to ensure that you have our latest content update. Content is updated daily, and updates will download to your device whenever you are connected to the internet and using the app.
