## What is ER & Rapid Response Training?

From emergency response to consciousness assessment, auscultation and history taking.
An educational app for practicing four core skills on the ward and in the ER: leading the initial response when a patient suddenly deteriorates, assessing impaired consciousness and finding its cause, telling heart and lung sounds apart, and narrowing the differential from the history. Work through 3D cases, real recordings and Q&A as often as you like.

■ Emergency Response Training
• Scenario simulation: A patient on the ward suddenly arrests. As team leader, take charge from recognition and BLS through defibrillation, drug administration and tracheal intubation to post–cardiac arrest care (3 cases, with scoring)
• Skill drills: 6 hands-on drills covering chest compressions, bag-mask ventilation, defibrillation, ECG, drugs and tracheal intubation
• Lessons: the BLS and ALS sequence, the 4 cardiac arrest rhythms, defibrillation, drugs, the 4 Hs and 4 Ts, and post–cardiac arrest care, taught with 3D visuals and quizzes

■ Consciousness Assessment Training
• Clinical mode: Watch how a 3D patient responds to voice and to pain, grade the JCS (Japan Coma Scale) and GCS, then work out the cause of impaired consciousness one question at a time (12 cases, about 2 minutes each).
• JCS quiz / GCS quiz: Practice scoring with 30 fictional cases, complete with timer, points and ranks
• Learn: JCS and GCS quick reference, Pupil atlas (try the pupillary light reflex in 3D), and AIUEOTIPS, the Japanese take on the AEIOU TIPS mnemonic

■ Heart & Lung Sounds
• Sound library: 102 recordings of 12 heart and 6 lung findings, from S3, S4 and murmurs to wheeze and crackles, by auscultation site, with waveforms and ECG timing
• Challenge mode: as many right answers as you can in one minute, at Beginner and Intermediate levels, with ranks and a review of your misses
• Listening quiz: listen, then choose from four answers (heart, lung or mixed; 10 questions a round)
• Recordings: HLS-CMDS (McMaster University, CC BY 4.0) and the University of Michigan Heart Sound & Murmur Library (CC BY-SA 3.0)

■ NEW: History-Taking Training
• 9 chief complaints, from headache and abdominal pain to dizziness and cognitive decline: how far can the history alone narrow the differential, without any tests?
• Answer Yes, Don’t know or No and watch the probabilities of 145 candidate diagnoses change. Can’t-miss diagnoses are flagged
• Differential lists, region-based differentials for numbness and abdominal pain, and disease cards with likelihood ratios. The probabilities come from a learning model based on published data

■ Who it's for
• Nurses, medical residents, paramedics and EMTs, and healthcare students
• Anyone who wants more confidence scoring JCS and GCS
• Anyone who wants to run through the BLS and ALS sequence hands-on
• Anyone who wants to feel surer listening to the heart and lungs
• Medical students and residents who want to build a differential from the history

■ PRO mode (one-time purchase)
• All 12 cases in Clinical mode of Consciousness Assessment Training (4 are free), Favorites, and retrying questions without scoring
• Unlocks cases 2 and 3 of the emergency Scenario simulation (case 1 is free)
• Heart & Lung Sounds: all 18 findings and 102 recordings, the listening quiz and the Intermediate challenge (free: 5 findings, 39 recordings and the Beginner challenge)
• History-Taking Training: all 9 chief complaints (headache is free)
• No ads
• Everything we add in the future is included
• No subscription. Restore your purchase on any device signed in with the same Apple Account.

Important: This app is for educational training only. All cases are fictional, and the patient responses shown are simulations for learning. Do not use it for diagnosis, treatment or any other real clinical decision. Always follow your institution's protocols and the judgment of physicians and other qualified professionals.

## Version history (last 5 releases)

### 1.9 — 2026-11-08

• The app is now called ER & Rapid Response Training.
• New: History-Taking Training. Across 9 chief complaints — headache, abdominal pain, numbness, low back pain, cough, chest pain, sore throat, dizziness and cognitive decline — see how far you can narrow the differential from the history alone. Every answer updates the probabilities of 145 candidate diagnoses, and you can browse differential lists, region-based differentials and disease cards. Headache is free; the other 8 complaints are in PRO mode.
• Other minor improvements.

### 1.7 — 2026-10-31

• New: Heart & Lung Sounds training. A library of 102 recordings of 12 heart and 6 lung findings, a one-minute Challenge mode (Beginner and Intermediate), a listening quiz, and auscultation tips (S1 vs S2, an S3/S4 animation, telling murmurs apart).
• A new PRO screen with short videos of each training. PRO mode also includes everything we add in the future.
• The app now focuses on three trainings: Emergency Response, Consciousness Assessment, and Heart & Lung Sounds. Procedure Training (Intubation Training and CVC Training) and the CVC and Intubation Full Plans are no longer offered.

• New: Intubation In Depth. 9 topics, from equipment and upper airway anatomy to laryngoscopy technique, confirmation and troubleshooting, plus a 13-question quiz — each one available straight from the menu.
• Clinical mode for consciousness assessment (12 cases): grade JCS and GCS from a 3D patient’s responses, then work out the cause. You can now also ask the patient’s name and whereabouts, or ask them to squeeze your hand.
• Real CT and MRI images, plus new learning pages including the Pupil atlas and AIUEOTIPS.
• Now available in Chinese (Simplified and Traditional), for a total of 10 languages.
• A new icon and a completely redesigned look.

### 1.5 — 2026-10-06

• Added a 3D patient model to make eye opening, verbal responses, and movement easier to observe.
