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. AHA ACLS offers an auto-renewing annual subscription at $3.99/year with a 3-day free trial. You will have unlimited access to all content while you maintain an active subscription. Payment will be charged to the credit card connected to your Apple ID Account when you confirm the initial subscription purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24-hours before the end of the current subscription period. Your account will be charged for renewal within 24-hours prior to the end of the current period. You may manage your subscription and auto-renewal may be turned off by going to your Account Settings after the purchase. Any unused portion of the free trial period, if offered, will be forfeited when you purchase a subscription. You can read more about our terms and conditions in the app.

- APP FEATURES - • CPR CYCLE CLOCK Tracks 2-minute compression cycles from the moment CPR begins. The cycle counter is always visible. Pause with a single tap when a shock is delivered, then resume a fresh 2-minute block; the cycle number carries forward correctly so the team always knows which round they're on. • CUSTOM DOSE TEMPLATES Independent per-drug timers with editable intervals and dose caps. Default templates for Epinephrine (q3 min, max 3 doses), Amiodarone, and Vasopressin ship pre-configured. Add your own templates for any med your protocol uses - name, color, interval, and max-dose cap are all configurable. Near-due and maxed-out states are color-coded. • SHOCK + PAUSE A dedicated yellow Shock button logs each defibrillation event and automatically pauses the CPR clock. Pause / Resume is also available manually whenever the team needs to stop or restart compressions. • ADD EVENT One-tap logging for rhythm observations (VF, pVT, Asystole, PEA), airway events (Intubation, LMA), fingerstick glucose, and free-text "Other" entries. Every event lands on the timeline with a timestamp. • HANDOFF SUMMARY When the code ends, a single screen presents the outcome (ROSC, Ceased, or Transferred with destination), the patient's initial rhythm, the medication list, the full chronological timeline, and free-text handoff notes. • EXPORTER - SHAREABLE PDF AND TEXT Copy a clean text summary to the clipboard for charting, or share a professionally-formatted PDF handoff through your phone's share sheet (email, AirDrop, Messages, Files). The PDF includes a stats grid, a color-coded chronological timeline, a medications table, the patient's initial rhythm, the outcome, and a signed timestamp. • HISTORY Every finalized code is preserved on the device for future review. Open any past code to re-read the timeline, re-export the handoff, or update its location label. - PRIVACY - Code Blue Flow runs entirely on your device. It collects no personal data, has no analytics or tracking, and makes no network connections. Session records are stored only in local storage on your phone and are never transmitted. Handoff summaries leave the device only through your phone's own share sheet, and only when you choose to export them. This app is a timer and note-taking tool. It is not a medical device and is not intended to provide medical advice, diagnosis, treatment, or clinical decision support. - IMPORTANT - Code Blue Flow is **a timer and a note-taking tool**, nothing more. It runs no protocols, makes no recommendations, and gives no clinical advice. It is not a medical device. Every elapsed time, dose count, and event entry shown in the app comes from what the user enters - the app does not infer, suggest, calculate, or guide. Use it at your own discretion as a supplement to (not a replacement for) your facility's protocols, your team's clinical judgement, the patient's official chart, and current AHA / ACLS guidelines. The team caring for the patient at the bedside remains the sole source of truth. The author assumes no liability for outcomes arising from use of this app. If something on screen is wrong, the team caring for the patient is authoritative - not the app.

Verdict
The clearest difference is in-app purchases: Code Blue Flow at none against AHA ACLS's 1. Code Blue Flow also leads on update cadence (every 2 days vs every 2 months) and iOS requirement (13.0 vs 15.1). AHA ACLS's advantage is ratings volume (277 vs 1) and chart position (#53 vs unranked). On price, rating, ads and device support there is nothing between them.

On the App Store both sit at effectively the same score — 4.9 for AHA ACLS against 5.0 for Code Blue Flow. That said, the two scores are not equally well evidenced: AHA ACLS has 277 ratings behind it against 1, so its average is the more settled of the two.
AHA ACLS ships an update every 2 months, Code Blue Flow every 2 days. The most recent releases landed on October 11, 2026 and October 6, 2026 respectively.
