# Kardia vs RedMed

The clearest difference is price: Kardia at Free against RedMed's $0.99. Kardia also leads on rating (4.8 vs 3.2) and ratings volume (239K vs 5). RedMed's advantage is iOS requirement (10.0 vs 15.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Kardia is free to download; RedMed costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Kardia holds the better App Store score, 4.8 against 3.2. That said, the two scores are not equally well evidenced: Kardia has 239K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 65% of Kardia's written reviews are positive against 67% of RedMed's, so the app with the better star average is not the one people write more warmly about.
