Update! Works on my iPhone XS Max

I love this app and use it all the time on shift, but ever since upgrading my phone the app is unusable. It gets stuck on “loading initial database.” Have tried uninstalling/reinstalling, resetting the phone, making a new account, but nothing works. I read the prior responses from the developer on here and have been on WiFi and used the blue update button, but it still gets stuck in the same spot. I emailed and haven’t heard back yet (it’s only been a few days though). Hopefully someone responds and we can get it working again. I appreciate all the work that’s gone into this amazing resource! UPDATE: I finally got it to work. I changed my screen lockout time to 5 min and that allowed the update to complete. Apparently the update process stops if your screen locks out or if you switch to another app (update process does not continue in the background.)

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.

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.
