## What is Critical Med?

Critical Med is a fast, fully offline study companion and reference for critical care clinicians — nurses, paramedics, residents, and attendings. It opens in one tap with no account and no sign-in, so your study material is always ready.

ACLS & RECERTIFICATION STUDY
- Over 800 clinician-reviewed practice questions with the reasoning behind each answer
- Timed 50-question practice exams scored against the 84% pass line
- 11 megacode practice scenarios, each with a review debrief
- Adaptive review that resurfaces the topics you keep missing

STUDY LIBRARY & REFERENCE
- Reference notes on meds commonly seen in critical care
- Over 500 IV compatibility reference pairs
- ICU infusion reference entries
- Lab value references with typical ranges and study notes

RHYTHMS & MONITORING STUDY
- 30 rhythms in an interactive practice simulator to build recognition
- Study guides for CBC, CMP, coagulation, and acid-base concepts
- Reference material on ventilation, capnography, hemodynamics, pacemakers, and ECMO

PROCEDURE & SCENARIO STUDY
- Illustrated procedure study guides
- 100 clinical study playbooks for less common scenarios
- Pediatric and obstetric study references

STUDY ANYWHERE, EVEN OFFLINE
Everything works offline with no account or sign-in, plus a fresh study brief every morning.

Important: Critical Med is an educational study and reference tool. It does not provide diagnosis, treatment directives, or emergency services, and it is not a substitute for professional clinical judgment or facility protocols. ACLS study content supports personal exam preparation only; it is not AHA-accredited and does not grant a certification card.

### 5/5 — Trusted Critical Care Calculator

*2026-07-21*

I am an OG Critical Care Flight Paramedic who has worked in critical care medicine for over thirty years. I always had to do all of my calculations in my head, or on paper. The process took about ten minutes to confirm all of my calculations. I still double check my calculations with this app, and it is perfect every time. When seconds count in Emergency and Critical Care Medicine; This is the App you need!

### 1/5 — No longer up to date

*2026-07-11, version 33*

I used to love this app but it is no longer current with aha guidelines (2015 ACLS) nor medical standards of care.  A waste of money. 😢

### 5/5 — CC Paramedic lifesaver!!!!!!

*2026-05-30, version 33*

This is one of my fast reference’s for the field!
It’s become my workhorse when things get hairy and I need offline info NOW!

### 3/5 — No support

*2026-05-12, version 33*

App is great, but it is missing the built in conversion factor to calculate Os on the EC135 single or double tank set up. There hasn’t been an update for 3 years, and the website for the dev is no good.

### 5/5 — What I need

*2026-02-25, version 33*

I love this app! It’s so helpful in the little rural critical access hospital I work at where the nurse is also RT, pharmacist, and lab. Can it be updated to reflect 2025 ACLS guidelines?

### 1/5 — Not great

*2026-01-19, version 33*

I wouldn’t download this for free! Had so many good reviews I gave it a shot. It’s terrible. I’m incredibly frustrated that I wasted my money. You have many resources at your place off employment that far exceed what is available on this app. Don’t bother.

### 5/5 — Great resource

*2025-06-17, version 33*

Love this app for quick access to pertinent information at my fingertips

### 5/5 — I don’t write reviews, get this app!

*2025-03-10, version 33*

This is HANDS DOWN the best app for emergency medicine. 911 EMS, or critical care transport. Seriously, I recommend this app to ALL of my colleagues every chance I get. This is such a necessary pocket tool to take to the field.

### 4/5 — Only one thing missing

*2025-01-21, version 33*

I love this app and I’ve been using it for years, both in the ER and on the ambulance. The only thing I wish it had was the ability to put in the ranges for drugs for my protocols so I could just put in the patients weight and see exactly what I need to draw up for IVP meds.

### 5/5 — Awesome!

*2025-01-09, version 33*

Everything at your fingertips! Great app and worth the price.
