The Journey
From Mechanism to Bedside
PathoPlay
Understand WHY diseases happen. Build the mechanism chain from trigger to outcome. Then learn WHERE drugs intervene.
MedDiagnosis
Apply that knowledge. Investigate a patient, order the right tests, make the diagnosis, choose the treatment.
PathoPlay builds the foundation. MedDiagnosis puts it into practice.
650+
interactive cases & puzzles
“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.”
