The MGH ACLS app was developed by Harvard-trained physicians, in collaboration with the American Heart Association (AHA), to help fellow physicians, physician assistants, nurse practitioners, and emergency medical technicians (EMT) deliver the highest level of advanced cardiac life support (ACLS) at the point-of-care. It began as a project to assist clinicians within Massachusetts General Hospital (MGH), a Harvard Medical School teaching hospital—and then expanded to have a national scope after significant positive impact was demonstrated. Importantly, real-time feedback from our clinician users continuously drives improvements in app design, features, and function.

MGH ACLS app is the only one to have all content vetted by both the American Heart Association (AHA) science team (with license to use ACLS content) and practicing Harvard-affiliated physicians. It is also the only one to feature the latest AHA recommendations during COVID-19 based on their latest scientific publication in Circulation.

We owe it to our patients to use the best digital health tools to give them the highest chance of surviving acute life-threatening cardiac illnesses. To this end, we have developed a free, intuitive, and rigorously vetted mobile app to assist healthcare clinicians— including in all stages of training—navigate ACLS at the bedside.


- Intuitive design to rapidly access 5 ACLS algorithms (i.e. cardiac arrest, cardiac arrest COVID-19, tachycardia with pulse, bradycardia with pulse, and post cardiac arrest care)

- Includes all ACLS content including drug therapy and dosing, reversible causes, etc.

- Easy-to-read timers and ability to log rounds of CPR, epinephrine, and defibrillations

- Button within cardiac arrest algorithm that allows for rapid transition to post cardiac arrest care pathway once patient achieves ROSC

- All content rigorously vetted by AHA science team and practicing Harvard-affiliated physicians

- Regularly updated with the most up-to-date ACLS content

A sincere thank you to all our colleagues battling COVID-19 on the frontlines. We welcome all your thoughts, comments, and feedback to make this app more helpful to you and your patients.

What’s New

Version 1.0.2

All code timers now run in the background, even when the app is minimized. We continue to iterate based on real-time clinician feedback, so that you will have the best experience providing life-saving care at the bedside. Thank you for all that you do, and we hope you and your loved ones stay healthy and safe.

I’m a practicing emergency physician. This is what I’ve been waiting for: an accurate, easy to use app for running codes and going through ACLS at the patient’s bedside. It also has the Harvard and American Heart Association seal of approval, so I know I can trust what I’m using. Every emergency medicine doctor’s dream come true.

There are way too many sketchy, unreliable, unwieldy—and sometimes dangerous—apps on the App Store that are advertised for running codes or going through the ACLS algorithms. I would know, because I have downloaded over half a dozen ACLS apps, all of which I have deleted because they were not practical to use at the bedside.

Doctors need tools they can 100% trust, especially when it comes to saving a life—this is it!

Give it a shot!

Full Disclosure: I’m one of the contributors and our team hopes you‘ll give this app a shot during the rapids/codes you run.

We think it’s the best solution on the market with all the ACLS info you’ll need to make the right decision (algorithms, drugs, doses) and timers built in to ensure you’re on track - the timers turn red at the algorithm-indicated time points, gently nudging you to take the next steps. Please do give us feedback as we are always working on improvements!

Great Digital Health Tool

Easy access to clear presentations of AHA ACLS algorithms! This is a great digital health tool that can help improve the efficiency and effectiveness and running codes and managing arrhythmias. Perfect complement for teaching residents and medical students on the internal medicine unit- a must have!
