# LA County Paramedic vs arrhythmia

The clearest difference is rating: LA County Paramedic at 5.0 against arrhythmia's 4.2. LA County Paramedic also leads on monetization model (free with in-app purchases vs subscription). arrhythmia's advantage is ratings volume (111 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. LA County Paramedic sells 3 in-app purchases, starting at $0.99 per month and arrhythmia sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

LA County Paramedic holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: arrhythmia has 111 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of LA County Paramedic's written reviews are positive against 45% of arrhythmia's, so the app with the better star average is not the one people write more warmly about.

LA County Paramedic ships an update every 5 weeks, arrhythmia every 3 weeks. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
