Why ScrubIn is different
OR turnovers are 15 minutes. Traditional study takes hours. ChatGPT hallucinates. Anki is brittle. UWorld is Step-focused. Surgical residents deserved a tool built for them.
Attending-style Socratic sessions
Ten questions per session. Each answer unlocks the next layer — the way attendings actually teach in the OR. Wrong answers don't just say "incorrect"; they show the consequence (flap ischemia, compartment syndrome, missed CSF leak) and walk you back.
Active recall · case → decision → consequence
Surgery-native, not Step-prep retrofitted
Built for PSITE, ABSITE, and OITE specifically. Categories, flap classifications, fracture taxonomies, and anatomy diagrams are surgical-residency-grade. Not surgery content tacked onto a Step-1 platform.
Mapped to PSITE / ABSITE / OITE blueprints
Designed for the 5 minutes between cases
OR turnovers are 15–20 minutes. Traditional study takes hours. ScrubIn's Daily Case fits in the gap. Streaks auto-freeze for tough call days. iOS notifications nudge at 7 AM and 8 PM — quiet otherwise.
iOS-native habit loop · offline-first PWA
Built for the way surgeons think
Stepwise reasoning, peer-reviewed content, and a habit loop sized for the 5 minutes between cases.
Board-mapped questions
2,500+ peer-reviewed questions aligned to PSITE, ABSITE, and OITE blueprints — every item tagged by board category.
Daily Case
One curated stepwise scenario every morning. The fastest 5 minutes of your day, with consequences when you guess wrong.
Spaced repetition (SM-2)
Per-question review at 1, 3, 7, 14, 30, and 60 days. Surfaces what's about to slip — not what you already know cold.
Layered teaching content
Every question carries Pearl, Pitfall, and Attending Tip cards. Diagrams show flap classifications, fracture taxonomies, and decision trees.
Miss Pattern Analytics
See your weak categories before your program director does. Confidence calibration surfaces overconfident misses as a metacognitive signal.
Offline-first
Study on the L, in the call room, or anywhere reception dies. Progress syncs when you reconnect.
Program cohort leaderboards
Join with a code, see your co-residents on the board. Customizable alias keeps it private when you want it private.
Reviewed, not AI-generated
Every question carries reviewer metadata — name, last reviewed date — visible to you and traceable. We do not generate clinical content with AI.
What we’re building next
Active roadmap. We ship what residents ask for, in the order they ask for it.

Zero percent correct.
I was studying. The problem wasn’t effort.
I couldn’t convert what I read into answers when an attending turned and asked me a question in the OR. The 15 minutes between cases — I spent them Googling. Frantically. In a panic.
0% correct.
That’s where I started. Not because I didn’t know the material — but because I had no structured system to retrieve it under pressure, in that context, in that moment.
Then I switched to active, Socratic, case-based recall — the way attendings actually teach in the OR. And I went from 0% to answering 25–50% of OR questions correctly.
That delta is ScrubIn.
