Stop Guessing.
Start Diagnosing.
A 71-year-old man is found slumped on a park bench, smelling of alcohol. His BAL comes back positive. Everyone relaxes. But his pupils are pinpoint, and he can hear everything you're saying. One choice saves his life.
Textbooks teach you the facts. MedDiagnosis trains you to use them. Board prep for USMLE Step 2 CK, PLAB 2, NEET PG, and OSCE.
Medical exams have evolved.
Your prep should too.
It's no longer just "What is the diagnosis?" It's "What is the next best step?" Most apps let you click until you get it right. We don't.
The Emergency Pack
Welcome to the ER.
Golden Hour Mechanic
Real-time pressure. Stabilize before time runs out.
Diagnostic Budget
Limited resources. Choose the right tests or run out.
12 Critical Cases
Ruptured AAA, acute stroke, and more.
Everything you need to
think like an attending.
Manage a patient from first presentation to recovery. Budget your workup, interpret results, treat complications — every decision has consequences.
The Sniper Mechanic
You have a limited budget. Build a focused differential — can you prove it with a precise workup, or will you waste thousands on a shotgun approach?
The Trap System
We don't just have wrong answers — we have Lethal Traps. Giving glucose before thiamine? Trusting a normal CT when the patient is seizing? You'll learn why the hard way.
The Stabilize Mechanic
Your patient is crashing while you wait for results. IV fluids, vasopressors, oxygen — choose wrong and you'll make it worse.
Treatment Mode
The job isn't done at diagnosis. Prescribe meds, manage complications, and decide: medical management or surgical intervention?
Instant Feedback
Clinical Pearls explain every outcome — why you failed, or why you succeeded. Learn from mistakes immediately.
100% Evidence-Based
Dedicated Reference Library citing Harrison's, UpToDate, KDIGO, and ACR/EULAR Guidelines. Every case is grounded in real medicine.
What our users are saying
"I encountered the exact same case on rotations that I practiced in the app. My preceptor praised me for knowing how to rule out and what tests to order."
Have you seen House M.D. and want to feel like the head of diagnostics? This is the app for you. The app gives you a budget and you're supposed to work within your budget to diagnose the patient correctly. I really can't think of any complaints.
This app is a helpful study tool for medical students practicing differential diagnosis. It's straightforward to use, great visuals and perfect for quick study sessions. Overall, a solid resource for students looking to improve their diagnostic thinking.
Very interactive. I'm not a medical student. My friend suggested it to me for my knowledge.

Absolutely. MedDiagnosis trains you for "next best step" questions — essential for Step 2 CK, PLAB 2, and the new NEXT pattern. It complements question banks by teaching you how to think through cases, not just memorize answers.
Question banks test recall. MedDiagnosis trains clinical decision-making. You get a limited budget (the Sniper Mechanic), face Lethal Traps that punish real clinical mistakes, and stabilize crashing patients while you wait for results. You manage patients from presentation to recovery — not just pick the right answer.
