The Journey
From Mechanism to Bedside
PathoPlay
Understand WHY diseases happen. Build the mechanism chain from trigger to outcome. Learn WHERE drugs intervene.
Kinetics
Master nutrition biochemistry through clinical reasoning. Built for the 2026 USMLE update — pathways, cases, and spaced repetition.
MedDiagnosis
Apply that knowledge. Investigate a patient, order the right tests, make the diagnosis, choose the treatment.
PathoPlay builds mechanism foundations. Kinetics masters nutrition biochemistry. MedDiagnosis puts it all 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.”
