As much as I love the physical copies of the Merck manuals (I have the first copy from 1899!), the online resource is ultra convenient when I want to check something on the go. I would suggest this app for just about anybody in the health professions who wants to remain knowledgeable in their field 👍🏼

*2026-06-06, version 4.1*

Update - The problem has been fixed in version 4.1.

The search feature has recently stopped working.  It shows results, but the spinning pinwheel never finishes so you can’t select any of the results.

I tried searching “acute pancreatitis” and got the pinwheel of death. Seriously? Yes, the app is synced and is the latest version, updated etc. Not acceptable.
