The AHA ACLS app is the American Heart Association's (AHA) officially endorsed digital health solution to assist clinicians in running codes and delivering bedside ACLS care with actual patients. The app was developed by Harvard-trained physicians, in collaboration with the AHA, to help fellow physicians, nurses, physician assistants, nurse practitioners, and EMTs 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 global scope after significant positive impact was demonstrated. Importantly, real-time feedback from our clinician users continuously drives improvements in app design, features, and function so that you will have the best experience providing life-saving care at the bedside. The AHA ACLS app is the only one to have all content vetted by both the AHA science team and practicing Harvard-affiliated physicians. It also features the latest 2025 release of AHA recommendations for ACLS. 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 low cost, intuitive, and rigorously vetted mobile app to assist clinicians— including in all stages of training—and enhance ACLS care at the bedside. Features: - Intuitive design to rapidly access 4 ACLS algorithms (i.e. cardiac arrest, tachycardia with pulse, bradycardia with pulse, and post cardiac arrest care) - Includes all recently released 2025 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 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.

Verdict
The clearest difference is review sentiment: CPR Now App at 83% against AHA ACLS's 26%. CPR Now App also leads on in-app purchases (none vs 1). AHA ACLS's advantage is rating (4.9 vs 4.6) and ratings volume (277 vs 13). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AHA ACLS sells 1 in-app purchase, starting at $3.99 per year. CPR Now App asks for nothing beyond the download.
AHA ACLS holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: AHA ACLS has 277 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 26% of AHA ACLS's written reviews are positive against 83% of CPR Now App's, so the app with the better star average is not the one people write more warmly about.
AHA ACLS ships an update every 2 months, CPR Now App every 6 weeks. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
