# NACSELD vs AHA ACLS

The clearest difference is in-app purchases: NACSELD at none against AHA ACLS's 1. NACSELD also leads on iOS requirement (13.0 vs 15.1). AHA ACLS's advantage is update cadence (every 2 months vs every 40 months) and chart position (#52 vs unranked). On price, ads 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. NACSELD asks for nothing beyond the download.

NACSELD ships an update every 40 months, AHA ACLS every 2 months. The most recent releases landed on October 3, 2026 and October 20, 2026 respectively.
