Code Blue CPR's advantage is in-app purchases (none vs 7) and review sentiment (80% vs 63%). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

CardioTrials holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Code Blue CPR has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of CardioTrials's written reviews are positive against 80% of Code Blue CPR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CardioTrials ships an update monthly, Code Blue CPR every 3 weeks. The most recent releases landed on September 18, 2026 and September 19, 2026 respectively.
