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 to 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.

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
4,200+ 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.
Adaptive review
Sessions adapt to what you got wrong and what's fading. Surfaces what's about to slip, not what you already know cold.
Layered teaching content
Questions carry 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.
Works offline
Study on the L, in the call room, or anywhere reception dies. Progress syncs when you reconnect.
Shared leaderboards
Compete with the wider ScrubIn community. Customizable alias keeps it private when you want it private. Opt out anytime in Settings.
Peer-reviewed content
Every question reflects current surgical practice and is reviewed by clinician contributors before publication. AI may assist with drafting; clinical accuracy is verified by humans.

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 to 50% of OR questions correctly.
That delta is ScrubIn.

Is ScrubIn really free?
Yes, free during beta. No credit card, no ads, no selling your data. We'll be transparent if and when we introduce paid tiers.
How is this different from UWorld, Anki, or Amboss?
Those tools are great, but they're either Step-focused or content-agnostic decks. ScrubIn is built specifically for PSITE, ABSITE, and OITE. Questions are mapped to the actual board blueprints, scenarios walk you through real OR decisions, and the spaced repetition is tuned around a resident call schedule.
Is the content peer-reviewed?
Every question and scenario is written or reviewed by surgeons. Each item carries reviewer metadata (name and last-reviewed date) that's visible inside the app. AI may assist with drafting; clinical accuracy is verified by humans before publication.
When is Android coming?
Working on it. iOS is live first because that's where our beta testers are. Drop your email to be notified when Android ships.
Who's behind ScrubIn?
Jane Ewing, a Plastic Surgery resident at Loyola, writes and curates the content. Nate Ewing, a product manager, builds the app. Two people, one kitchen table in Chicago, one Golden Retriever puppy named Koji.
Is this affiliated with a hospital or program?
No. We are an independent LLC. We do not claim institutional endorsements. Any content reflects published surgical education guidelines, not formal endorsement from any specific institution.
How do I report a bad question or clinical inaccuracy?
Every question has an inline flag option in the app. Reports go straight to the medical reviewer team. We read every one.
Android coming soon. Get notified.
One email per shipped milestone. No spam, no sales.
Free during beta. No card required.
No ads. No data sold. We’re building this with residents. Once we know what’s worth charging for, we’ll be transparent about it. Right now, free.
