I love Merck Manual and have used the handbook in practice for over a decade. I've also used the website, so I was excited to finally use the app. However, I was sorely disappointed that the app has not been updated to support Android 11. IF you download the app and don't try to update, you can still access some content and features which is why I've given 2 stars. But if you accidentally forget and try to update, the app will freeze and be unusable until you uninstall even w/ stable wifi.

It's...okay. I'm adding a little more than an okay rating because it is, after all, still the Merck Manual. I remember the good ol' days when my then-girlfriend had bought me the Millennium Edition Merck Manual for Christmas and I read that thing literally from cover to cover at least twice in the first month of owning it. Anyway, I didn't give it 5 Stars because it keeps asking me to update it and when I click on the link, it brings me here and no update in sight. So? Where's the fire? Hello?
