# CathSource vs Cardiovascular Medicine

The clearest difference is rating: Cardiovascular Medicine at 3.0 against CathSource's 1.6. Cardiovascular Medicine also leads on iOS requirement (9.3 vs 18.5). CathSource's advantage is in-app purchases (none vs 10) and ratings volume (24 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Cardiovascular Medicine sells 10 one-off in-app purchases. CathSource asks for nothing beyond the download.

Cardiovascular Medicine holds the better App Store score, 3.0 against 1.6. That said, the two scores are not equally well evidenced: CathSource has 24 ratings behind it against 1, so its average is the more settled of the two.

CathSource ships an update every 2 months, Cardiovascular Medicine every 7 months. The most recent releases landed on October 22, 2026 and September 29, 2026 respectively.
