Learn biostatistics by
solving real clinical cases.
A gamified trainer for medical students, residents, and researchers. Spaced repetition, XP, 30+ case scenarios drawn from real biomedical research.
Works in-browser. Your progress saves automatically.
Built for how people actually learn
Not another passive video course — active recall, spaced repetition, and context-rich cases.
Spaced repetition
Questions you miss come back when you're about to forget them. Built on the SM-2 algorithm used by Anki.
Real case scenarios
Each case has a clinical story — critique a manuscript, advise a resident, design an RCT. Questions live in context.
Deep dives, not just answers
Every question links to intuition, formula, assumptions, pitfalls, and suggested reading. Learn the why.
XP, streaks, achievements
Gentle gamification that rewards consistency. Daily streak bonus, perfect-run badges, hard-mode multipliers.
Progress tracking

Free, forever
Everything unlocked. No ads. No dark patterns. Built by a researcher who wishes this existed in grad school.
Eight domains, from fundamentals to advanced
Who is this for?
Medical students & residents
