# Eko vs AHA ACLS

The clearest difference is monetization model: Eko at free with in-app purchases against AHA ACLS's subscription. Eko also leads on review sentiment (51% vs 26%) and ratings volume (11K vs 391). AHA ACLS's advantage is iOS requirement (15.1 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Eko sells 2 in-app purchases, starting at $12.99 per month and AHA ACLS sells 1 in-app purchase, starting at $3.99 per year. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Eko against 4.9 for AHA ACLS. That said, the two scores are not equally well evidenced: Eko has 11K ratings behind it against 391, so its average is the more settled of the two. Written reviews are what separate them: 51% of Eko's written reviews are positive against 26% of AHA ACLS's.

Eko ships an update fortnightly, AHA ACLS every 2 months. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
