Added: I do not understand all of the poor reviews over having to repurchase this app. Ongoing costs are incurred by the developer to keep the guide updated with the latest info, latest abx, etc, as well as updates for the various software platforms. Virtually ALL apps in medicine are on the subscription model for this very reason.

Original review: Clearly laid out. Easy to quickly find the info that I need in my daily practice. This app combined with UpToDate are my go-tos. (Yes, UTD has abx info, but again, the JH app is so user friendly.) Worth the asking price. This is my 3rd year to subscribe. I’ve also tried Sanford Guide, but this app’s layout was easier for me to find the info I need. YMMV.

Excellent experience

I had never before had to call with help for the products since owning them for years until now. The prompt response was unprecedented compared to other services I’ve used; the experience, knowledge and efficiency of service provided was great. By the way the experience using chat and telephone calls were phenomenal. Great job.

Well worth every penny

I work as an ID fellow and I wouldn’t be able to survive fellowship without this app. It’s essentially an ID textbook available at your fingertips. It works very well and updates constantly to give the latest info possible. I plan to re-up every year!!!

Developer Response ,

Thanks so much for using the app and for your review! Our goal as a company is to provide a way for the medical community to have rapid access to updated and accurate medical reference materials.
