# AHA PALS vs AHA Knowledge Booster

The clearest difference is monetization model: AHA Knowledge Booster at free with in-app purchases against AHA PALS's subscription. AHA Knowledge Booster also leads on rating (4.8 vs 4.5) and ratings volume (569 vs 54). AHA PALS's advantage is chart position (#138 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AHA PALS sells 1 in-app purchase, starting at $3.99 per year and AHA Knowledge Booster sells 4 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.

AHA Knowledge Booster holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: AHA Knowledge Booster has 569 ratings behind it against 54, so its average is the more settled of the two.
