WHAT'S INSIDE

Eight modules,
fully built out.

Every screen below is the shipping app, not a mockup. Guest mode is a device-local preview; a free account unlocks the full iOS app and sync.

Question Bank

850+ clinical questions, with the reasoning spelled out.

The question bank spans cardiovascular, respiratory, neuro, renal, metabolic, and multisystem critical care. Every answer opens into the reasoning; newer items carry a structured rationale with why-correct, why-wrong for each distractor, a clinical pearl, and citations. Guest mode includes a 150-question preview; a free account unlocks the full bank, flags, timers, custom tests, review queues, and spaced repetition.

Why Correct / Why Wrong Not an answer key: each option gets its own reasoning, so the distractors teach as much as the answer.
Clinical Pearls The pattern worth keeping, pulled out of the rationale and into a pearl you can carry to the bedside.
Category Tracking Accuracy by system over time. Find the gap, then close it.
Spaced Repetition Missed questions return on the right day. Easy ones space out. The system optimizes your time.
Per-Session Shuffle Answer letters shuffle every session, so you learn the content, not the position.
Custom Tests & Flags Build focused sets by topic, count, and timer; flag anything to revisit on your terms.

Simulation

Run the case. Watch the physiology answer.

Bedside simulation drops you onto a live monitor with a deteriorating ICU case. Make a call (a drug, a vent change, a pacer setting) and the modeled physiology responds. Guest mode opens the Basic Vitals workspace; a free account unlocks the pacer, Swan/CCO, and ventilator workspaces.

Real-Time Monitor ECG, arterial line, pleth, and respiratory traces trend together with the case.
Clinical Workspace Scenario, actions, labs, response, and log: the whole encounter in one place.
Modeled Physiology Pressure, flow, and gas exchange respond to what you do, not to a fixed script.
Debrief Every case closes with what improved the patient and what did not, tied to the scenario objective.

Hemodynamics

Hemodynamics, from circuit to shock call.

The deepest module in the app: a live hemodynamic circuit, a ten-module curriculum, and drill modes shaped around how clinicians actually build hemodynamic intuition: pattern first, numbers second. Guest mode opens the starter modules; a free account unlocks the full pathway.

Hemodynamic Circuit Pump, tank, and tone: a living model that shows how MAP, CI, SVR, and CVP move together.
Shock Recognition Read real ICU values. Name the shock: broad family, then specific subtype.
Clinical Decisions You have the profile. Choose the intervention: fluids, pressors, inotropes, and more.
Build the Profile Mastery mode: given only the shock type, reconstruct the entire hemodynamic profile from memory.
Escalation Arcs One patient, three turning points: the full deterioration arc from recognition to escalation.

Hemodynamics module: animated circulation circuit with MAP, CI, SVR, and CVP readouts above the curriculum.

EKG Trainer

EKG that teaches you to read, not memorize.

Anatomy → strips → lead-by-lead infarct localization. Each layer reinforces the previous one so rhythm reasoning becomes automatic instead of recalled. Guest mode starts the foundation path and rhythm references; a free account unlocks the full trainer.

Conduction Anatomy How the signal moves through the heart, mapped onto the surface EKG so you read with mental geography.
Rhythm Reference A clean, scrollable rhythm library, from sinus tach to torsades, with the distinguishing features pulled out.
12-Lead Territory Lead-by-lead infarct localization: which artery feeds which territory, which leads cover which wall.
Test Yourself Self-graded practice with focused feedback on what you missed and why.

Study Modules

Concept first. Then check yourself.

Each study module works one ICU domain end to end: teach the concept, then check yourself, so understanding builds before speed. Eight topics, from vasopressors to advanced ICU reasoning. Guest mode opens the first two modules in each curriculum; a free account unlocks the full set.

Vasopressors Match the shock state to the right pressor. Recognize when to add an inotrope, and when fluids come first.
Labs Critical values, electrolyte derangements, and what to act on now.
Fluids Resuscitation, maintenance, replacement: when to pick which, and why.
ABG Acid-base interpretation step by step. Mixed disorders included.
Ventilator Mode selection, troubleshooting alarms, weaning, and dyssynchrony recognition.
Pharmacology Receptors, infusions, and the ICU formulary: how the drugs work before you reach for them.

Medications

ICU pharmacology, from receptor to bedside.

A dedicated home for ICU drugs (pressors, sedation, anticoagulation, antimicrobials, and the high-stakes infusions), built as a curriculum that runs from receptor to dose to titration, with case practice that makes you choose. Guest mode includes the reference and a question preview; a free account unlocks the full curriculum, spaced review, and cases.

Med Station Six drug bins (vasopressors to analgesia) organized the way you reach for them.
Pharmacology Curriculum Receptors and infusion physiology, class by class: concepts before numbers.
Case Practice Bedside medication decisions: hold, continue, reverse, escalate, or choose the safer option.
Built for Infusions Pressors, inotropes, and sedation: mixing, dosing, and titration for the drips you run.

Medications module: med station with six drug-class bins and the pharmacology, questions, and case practice paths.

Clinical Tools

Reference, calculators, protocols. One tap from home.

The tools section is built for the moments you need a reference between cases, not when you have time to crack open a textbook. Guest mode keeps core references and basic tools available; a free account unlocks advanced calculators, protocols, specialty guides, and device trainers.

Calculators MAP, CI, SVR, P/F ratio, anion gap, IBW (Devine), free water deficit, Fick CO. Educational implementations of standard published equations.
ICU Protocols Sepsis bundle, ARDS, post-cardiac arrest, DKA, withdrawal scales, all organized by category and color-coded by domain.
Drug References Indication-first organization. What you reach for, not the alphabetical position.
Ventilator Modes Pressure vs volume, control modes, weaning modes, troubleshooting flowcharts.
Device Guides Pacers, IABP, CRRT: the basics you need before the conversation starts.

Clinical tools: bedside reference tables with normal hemodynamic ranges, plus calculators, guides, and device tabs.
