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.

Can't sign in

Great app but suddenly cannot log in through the app on my 6s. Keeps giving incorrect password. Message popped up sending me a new temporary password. Tried that on the app and did not work. Signed in on a browser on my 6s and was able to change password and log in with the browser but not with the app. Still says incorrect password. Deleted and reinstalled app but still incorrect password. Relying on browser for now.

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 Some in the data seems out of date but it’s still a good resource for your knowledge base.
