The Best Emergency Medicine App Is the One You Open Between Patients.

Bed 9 is a 4-year-old at 16 kilos who needs ketamine for a forearm reduction. Bed 3 wants to know if the ankle needs an X-ray. The charge nurse is asking whether the C-collar in bed 12 can come off. You have a phone in your pocket and about 40 seconds before somebody else needs you.

An emergency medicine app needs to make the dose, rule, or criteria easy to find between those interruptions. A long topic list is useful only if you can reach the relevant entry quickly.

The best emergency medicine app is the one you can open between patients and trust. It answers in seconds, works without a signal, covers pediatric dosing and the decision rules you use every shift, shows its references, and lets you ask a real clinical question in plain language when the answer is not a lookup. palmEM AI, built by emergency medicine physicians and in EM pockets for over a decade, was designed around exactly that test.

Find the answer quickly

At the bedside, you may need one dose or contraindication from a much longer topic. The app should make that detail easy to find without requiring you to read the whole chapter.

palmEM AI's average use time is 59 seconds. The content is organized for short lookups: a dose, a contraindication, a set of criteria, or the next step. You open the app, get the answer, and put the phone away.

Test any app the same way. Time yourself from unlocking the phone to reading the ketamine dose for a 16-kilo child. Notice how many taps and how much reading it takes to reach the answer.

It has to work with no signal

Data connections can be unreliable in trauma bays, CT suites, older hospital wings, and rural departments.

palmEM AI's quick reference content is available offline. Algorithms, dosing, procedure checklists, and the pediatric tape open the same way with or without a signal. The AI assistant, which needs a connection, sits alongside the offline reference rather than replacing it.

Pediatric dosing and the weight-based tape

Weight-based dosing and equipment sizes need to be easy to check during pediatric care. Look for a reference that puts those details together.

palmEM AI includes a virtual weight-based pediatric tape with resuscitation drugs and equipment sizes, plus a pediatric resuscitation section that clinicians describe as a must-have. One reviewer put it plainly:

"As a resident, it is a handy quick reference for treatment algorithms ranging from CAP abx coverage to the Pedi tape that has all your weight-based drugs. Best app in its category and allows you to quickly access the information needed."

The decision rules you use every shift, in one place

Ottawa ankle and knee, Canadian C-spine, PERC, Wells, HEART, PECARN. You know them, but you do not want to reconstruct them from memory at 3 AM with a patient asking whether they need the X-ray.

palmEM AI groups the validated rules under their own heading so you can find them without searching, then documents the criteria in the language you will chart. Procedure checklists, medication categories, and topic-by-topic pearls are organized the same way: by how you look things up on shift, not by textbook chapter.

Sources you can see, and no advertisers

Check who selects the content, how it is referenced, and whether advertisers influence it. palmEM AI is fully referenced and has no influence from advertisers or industry. Every entry is selected and updated by emergency medicine physicians who work the shifts you work, and the content is updated regularly as evidence changes.

That matters more now that AI is in the mix. When you ask an AI assistant a clinical question, you want it grounded in a curated EM knowledge base, not the open internet.

When the answer is not a lookup

Some questions need more context than a quick lookup provides. A 68-year-old on apixaban with a minor head injury and a normal exam. A rash you half-recognize. A pediatric dose for a drug you use twice a year.

palmEM AI's AI reference takes the question in plain language and answers from the same curated emergency medicine knowledge base as the quick reference: differential diagnoses for a complex presentation, treatment protocols, medication dosing and contraindications, procedure techniques, ECG and imaging interpretation guidance, and risk stratification. You ask the way you would ask a colleague. You get an answer you can act on and check.

Notes and bookmarks that make it yours

Notes and bookmarks let you keep local details beside the reference material. palmEM AI lets you add your own notes to any topic (your department's sepsis bundle, the ortho group's splinting preferences, the pharmacy's dosing quirks) and bookmark the pages you open most. That keeps frequently used pages and department-specific notes easy to reach.

Who it is for

Emergency medicine attendings, residents, PAs, NPs, paramedics, and students, plus urgent care, family medicine, and internal medicine clinicians who see the occasional ED-type patient. One family medicine reviewer described it this way:

"Absolutely worth the money! As a Family Med doc in clinic, this is my one-stop shop for the occasional ED-type patient that somehow schedules an acute appt with me instead of going to an ED. It allows me to perform quick interventions while coordinating transfer."

palmEM has 100,000+ downloads, is used by clinicians in 180+ countries, and has been the emergency medicine app in EM pockets since 2011.

The same reference, inside your charting

If you also chart in the ED, the same palmEM knowledge base lives inside palmER AI Suite, the emergency medicine charting platform from the same team. palmER listens at the bedside and drafts your HPI and Physical Exam, writes a structured MDM in seconds with the differential, risk, data reviewed, and disposition rationale, and puts the palmEM reference beside the note so you can ask the clinical question without leaving the chart. palmEM AI subscribers get that reference inside palmER.
