Verdict

The call

The clearest difference is review sentiment: Cardiology Cases at 73% against Pass CCRN's 20%. Pass CCRN's advantage is rating (4.6 vs 4.2) and ratings volume (608 vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Pass CCRN sells 2 in-app purchases, starting at $24.99 per month and Cardiology Cases sells 14 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Pass CCRN holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Pass CCRN has 608 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 20% of Pass CCRN's written reviews are positive against 73% of Cardiology Cases's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pass CCRN ships an update every 3 weeks, Cardiology Cases every 4 weeks. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
