Version 2.0.1

Version 2.0.1:
- Various bug fixes and performance improvements.

Love it but make the app better

Hi, I think amboss is an amazing resource. I am in my preclinical years and this is by far the best bang for your buck. The questions range from easy to hard, and I mean challenging your mind brain hurts hard. The explanations are fabulous and the integration between the library and knowledge is nothing spectacular but gets the job done. The reason why I didn’t give this 5 stars has nothing to do with the quality of amboss but the app doesn’t allow you to highlight key things in the passage which is a super downfall because that’s how I take my tests. Also, I only use my iPad for school so I cannot reap the benefits of using the amboss Anki add on on my iPad, which is disappointing. Overall love the app and recommend it for anyone who wants to challenge themselves and be a better doctor.

Developer Response ,

Hey Phil, thanks so much for your review. We are so glad that you love our content! The ability to self-highlight text manually in our Knowledge app is a great suggestion and I can understand why this would be so useful for you. I have passed this suggestion directly on to our Product team. In the meantime, you can use the AMBOSS Highlight feature which can be found in each of our articles. This feature will highlight the high-yield information relevant to your study objective. Please make sure to keep your study objective up to date to get the most of this feature, you can change it at any time in the Account Settings > About me section.

Our Anki add-on does not support the mobile version of Anki because of the technical limitations associated with this version of the Anki app. This is something that may change in the future, and we are looking forward to being able to build an AMBOSS Anki add-on which will be compatible with the Anki mobile app.

The Best Medical Library for USMLE

I got to know AMBOSS in the middle of my preparation for USMLE /step 1 last year. Currently I use it for step 2 CK preparation

It is the best medical library you can find for the preparation for many reasons :

1 . Very well organized topics

2. Excellent illustrating images and videos

3. High resolution histopathological images with labels which made me improved in the weakest part I was in

4. Q bank with very close similarity to the real exam

And too many other reasons

Yes can not recommend it enough for everything me there

Knowledge App stopped working

Before, this app was working great to complement any knowledge I wanted to refer to on my iPhone. Recently within the last month, the knowledge app keeps saying ‘Oh no, you can’t access this right now and the error seems to be on our side’. I find this has been detrimental to my learning from a full AMBOSS experience, and I had tried everything from reinstalling the app to signing in again but with no luck. Please address this!!!
