Excellent concept, but onboarding gap undermines learning
I like the core idea of this app—case-based diagnostic reasoning is exactly what trainees need. However, there is a critical issue with how scoring is presented versus how users are instructed.
There is no upfront explanation of how answers are graded. As a result, I initially approached cases by building a broad differential (which is a valid clinical strategy), assuming that having the correct diagnosis included would be sufficient.
Instead, the app grades heavily based on ranking and early prioritization, not just inclusion. In my case, I correctly identified the diagnosis, but because it was lower in my differential list, I received a score of 0/30.
This creates two problems:
1. Mismatch between user expectations and scoring system
2. False negative feedback, where correct reasoning is effectively scored as failure
This is not a knowledge issue—it’s a communication issue.
A brief onboarding or tutorial explaining:
- That differentials must be ranked by likelihood
- That earlier identification improves scoring
- How hints affect grading
would immediately resolve this.
As it stands, the app risks losing users early—especially trainees—because it feels like being graded incorrectly rather than being taught. Receiving a near-zero score despite identifying the correct diagnosis is discouraging and undermines trust in the feedback.
The tool has strong potential, but the lack of clear instructions actively detracts from the learning experience.
If clear guidance is added upfront, I would strongly consider revising this to a 5/5, because the underlying product is genuinely valuable.

Love this app
Love the cases. Both interesting and relevant

Great exposure
Great application
I find this application awesome. It features great cases. There is a learning component to it and the ability to collaborate with others. The teaching points make it an academic exercise and allow one to build on their foundation of knowledge. I think it would be a great resource in the educational, post graduate, and professional settings. There are also points someone can accumulate which makes it fun like a game, too

This is how medicine should be
I really like it. One learn while also providing help. Very nice.
Very helpful cases!
Excellent cases! Very practical. I wish I could do these cases on my desktop...

Great App !!!
Best collection of cases in the best structure
Espetacular! Amazing app!
One of the most amazing ever! Great idea! Funny and informative app for students and experienced doctors!
Could be much better
I like the idea behind this app but there are a few big obstacles for me. First, please make an iPad or webapp version so I’m not forced to use my phone . A phone interface is so clunky for medical diagnoses, especially ones with long names. Second, better formatting, some of these cases are massive blocks of text with lab results, ROS findings, physical exam findings, etc.

Best app ever!
This is engaging and challenging. Absolutely love it!!
Recommend app for GP and medical students
So good to use
The best
Best app to learning w/ clinical cases.
Human Dx
Human Dx is a great way to practice developing differential diagnoses and to learn clinical pearls for solving clinical problems
Great way to learn
Really easy way to get morning style learning in a digestible way, great cases with well written summaries
Good for experienced docs and learners
This looks like to will be a great tool for learners struggling with medical knowledge but a good refresher for us old docs too
Morning report
A daily refresher to sharpen the clinical problem solving.
An excellent app for busy doctors
I really enjoy using this app as part of my daily routine as it allows me to keep abreast of clinical presentations and rapidly assimilate the knowledge to sharpen my clinical reasoning. Thank you for a great app
New student
This app is wonderful and a little addictive
