Heart Sounds
Cardiac Auscultation
- Phonocardiogram with toggleable S1/S2/murmur labels as visual hints
- Dynamic auscultation — Valsalva, squat, handgrip, leg raise, etc.
- Diaphragm vs. bell stethoscope modes; live respiration controls
Interactive simulators, hierarchical reference, and active-recall tools covering 11 body systems — heart sounds you can hear, EKGs you can synthesize, 1,162 conditions, 625 medications, six imaging modules, and high-yield study charts. Built for med students who want to build real clinical reasoning, not just memorize.

Evidence-Based Medicine
Not flashcards. Not lecture recordings. Interactive tools designed around evidence-based learning science.
Heart sounds are synthesized in real time using the Web Audio API — not recorded clips. Change the pathology, maneuver, or heart rate and hear the difference instantly.
Every question maps to a medical concept graph. Aortic stenosis in auscultation links to its EKG pattern, its hemodynamics, and its biostatistics — building integrated clinical reasoning.
The question engine prioritizes concepts you're weakest on, factors in how recently you reviewed them, and adjusts urgency if you have an exam coming up.
Questions resurface at optimal intervals based on your accuracy and time since last review. Mastered concepts fade into the background; weak spots come back more often.
Practice with USMLE Step 1 and Medicine Shelf blueprints that weight concepts the same way the actual exam does. See your readiness score update in real time.
Order 1 (name that murmur) through Order 4 (full clinical vignette). As you master individual skills, integration questions combine them into real diagnostic reasoning.
