Realistic AED simulator for CPR training. Built for iPhone and iPad. No ads. No tracking. ## Features - Authentic simulation of an AED (Automatic External Defibrillator). Realistic voice prompts, button clicks, sound effects, graphics, animations and flashing lights. - LED displaying instructions, number of shocks, and CPR countdown timer. CPR metronome provides beats at 100, 105, or 110 BPM (beats per minute). This ensures CPR compressions at the correct frequency. - Scenario editor allows for custom or random scenarios. - All prompts, messages, timing, and voices are customizable. You can change any message or voice prompt to match any AED. - Allows for user provided backgrounds, sound effects, and even metronomes. Drop an MP3 of Staying Alive into the Metronomes directory to do compressions to the Bee Gees. - Adheres to 2020 CPR Guidelines. - Universal app supports iPad. - Great price. ## Details An AED is a device used to provide a shock of electricity to somebody in cardiac arrest (having a heart attack). Defibrillation is the definitive treatment. Knowing how to use an AED is an important skill for firefighters, EMTs, paramedics, nurses, doctors and general public. AED Sim gives people a chance to see, hear and interact with an AED. If you have ever been curious about how one operates now is your chance. The built-in scenario editor lets you create a custom scenario or it can generate a random scenario for you. Combine an iPhone or iPad and AED Sim and youʼve got an inexpensive realistic training environment for practicing CPR. No costly AED trainers needed. Designed and built by a former Canadian paramedic with 20 years of software development experience.

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. The AHA PALS 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 pediatric advanced life support (PALS) at the point-of-care. This project was inspired by the tremendous success of our AHA ACLS app, which has thousands of clinician users in over 180 countries. Importantly, real-time feedback from our clinician users continuously drives improvements in app design, features, and function. AHA PALS is the only app to have all content vetted by both the American Heart Association (AHA) science team (with license to use PALS content) and practicing Harvard-affiliated physicians. We owe it to our patients to use the best digital health tools to give them the highest chance of surviving acute life-threatening illnesses. To this end, we have developed an intuitive and rigorously vetted mobile app to assist healthcare clinicians—at any stage of training—navigate PALS at the bedside. You can purchase a yearly subscription which begins with a 3-day free trial. After completing the free trial, you will be charged for an annual subscription automatically. Features: - Intuitive design to rapidly access PALS pathways (i.e. cardiac arrest , tachycardia with pulse, bradycardia with pulse, post cardiac arrest care, and critical care references) - Includes all PALS content including drug therapy and dosing, reversible causes, etc. - Easy-to-read timers and ability to log rounds of CPR, epinephrine, and defibrillations. There are additional functionalities to log PALS Cardiac Arrest interventions beyond EPI, CPR , and shocks such as lidocaine and more. - We also added a new metronome feature to improve compression accuracy as well as a ROSC button. - Button within cardiac arrest algorithm that allows for rapid transition to post cardiac arrest care checklist once patient achieves ROSC - Relevant critical care references: (1) drugs used in PALS (i.e., medication names, indications, and doses); (2) vital signs in children; (3) pediatric color-coded length-based resuscitation tape (adapted from Breslow tape) ; (4) pediatric Glasgow Coma Scale - All content rigorously vetted by AHA science team and practicing Harvard-affiliated physicians - Regularly updated with the most up-to-date PALS content

Verdict
The clearest difference is price: AHA PALS at Free against AED Sim's $2.49. AHA PALS also leads on update cadence (every 2 months vs every 44 months) and ratings volume (53 vs 4). AED Sim's advantage is in-app purchases (none vs 1) and rating (4.8 vs 4.5). On review sentiment, ads, chart position and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
AHA PALS is free to download; AED Sim costs $2.49 up front. AHA PALS sells 1 in-app purchase, starting at $3.99 per year. AED Sim asks for nothing beyond the download.
AED Sim holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: AHA PALS has 53 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of AED Sim's written reviews are positive against 55% of AHA PALS's, so the app with the better star average is not the one people write more warmly about.
AED Sim ships an update every 44 months, AHA PALS every 2 months. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
