# CathSource vs AnticoagEvaluator

The clearest difference is rating: AnticoagEvaluator at 2.3 against CathSource's 1.6. AnticoagEvaluator also leads on monetization model (free vs paid) and iOS requirement (11.0 vs 18.5). CathSource's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (24 vs 3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AnticoagEvaluator holds the better App Store score, 2.3 against 1.6. That said, the two scores are not equally well evidenced: CathSource has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 38% of CathSource's written reviews are positive against 30% of AnticoagEvaluator's, so the app with the better star average is not the one people write more warmly about.

CathSource ships an update every 2 months, AnticoagEvaluator every 7 months. The most recent releases landed on October 22, 2026 and October 12, 2026 respectively.
