# AHA ACLS vs ACP MKSAP

The clearest difference is rating: AHA ACLS at 4.9 against ACP MKSAP's 4.2. AHA ACLS also leads on ratings volume (377 vs 17) and chart position (#39 vs unranked). ACP MKSAP's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (57% vs 26%). On price, ads, in-app purchases 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 and ACP MKSAP sells 1 in-app purchase, starting at $999.99 per year. Whichever you choose, the download price is not the number that matters.

AHA ACLS holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: AHA ACLS has 377 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 26% of AHA ACLS's written reviews are positive against 57% of ACP MKSAP'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, ACP MKSAP every 10 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
