This is a great app. And at no charge! It is easy to navigate and has great colored pictures. I wish I had this sooner. The downloading was easy....I just made sure I had a good connection. Well worth doing!

This Vet will stick with print version!

It is unbelievable that Merck, a renowned company with a more renowned veterinary reference book can’t supply an app that actually works. I am beyond disappointed AND frustrated after repeatedly attempting to download, install, uninstall, and reinstall numerous times. The app will simply not install onto my iPhone 7 or iPad Pro regardless of high quality internet speed and an over abundance of patience. I’m obviously not the only person out here having this same issue and it’s NOT because I can’t follow simple directions. The ***notation on the app store suggesting we just need to “install it right” in response to numerous complaints is beyond patronizing.
Thanks for nothing Merck. It’s a shame because when I went to veterinary school, the Merck Manual was almost entirely what we studied before our board exams. Such a wonderful reference, but the app is a big pile of “feces”.

Developer Response ,

We regret that you are having trouble. Please contact for assistance. We investigated and discovered that the app requires 300 MB of free space to initialize or it freezes without warning. We will address this in the next release. We are also developing a smaller version of the app that accesses multimedia online.
