Good update

The app was just updated for the iPhone X and now things seem to be working well. Hyperlinks has been broken for a while, but now seem to be working again.
This has become my go to app on shift, replacing several other expensive options like pepid and UpToDate! The app is fast, concise, has great information, and is free!! Hard to beat.

Great website, horrible app

I love the website. It’s very helpful, a resource I used often during training, and something I turn to on shift sometimes for a refresher or reassurance. However the app is unusable. No matter what I do it cannot download the database. It will say “downloading content” for days without change. Even in previous versions when it could download the database the search bar would end up with no results. Now the search bar doesn’t do anything and the clinical pages are empty. To be honest for the last two to three years the quality in this app has become extremely poor but now I would tell trainees and colleagues to avoid this app.

Developer Response ,

I'm sorry you have had such a frustration. I can assure that I am working to make the offline content more seamless but I can also assure that this app does indeed work on an iphone XR which I am using right now. Please connect to wifi and click the blue update button to allow a full sync and you will be good to go in less than a minute.

Pretty good study tool

Great once I figured out how to download the database! I don’t use this in clinical practice but it’s a good study tool to refresh on topics I’m interested in. Some in the data seems out of date but it’s still a good resource for your knowledge base.
