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.

Verdict
The clearest difference is price: AED Sim at $2.49 against SimMon's $22.99. AED Sim also leads on rating (4.8 vs 4.5). SimMon's advantage is update cadence (every 5 months vs every 44 months) and review sentiment (67% vs 50%). On ads, in-app purchases, monetization model and chart position 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
AED Sim costs $2.49 and SimMon $22.99 up front. Neither carries in-app purchases, so what you see is what you pay.
AED Sim holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 4 and 13 respectively. Written reviews complicate that: 50% of AED Sim's written reviews are positive against 67% of SimMon'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, SimMon every 5 months. Both last shipped on November 6, 2026.
