# Heart Graph vs Cardiograph

The clearest difference is price: Heart Graph at Free against Cardiograph's $1.99. Heart Graph also leads on review sentiment (87% vs 57%) and update cadence (every 2 weeks vs every 5 weeks). Cardiograph's advantage is iOS requirement (8.0 vs 15.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.

Heart Graph is free to download; Cardiograph costs $1.99 up front. Heart Graph sells 2 one-off in-app purchases and Cardiograph sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cardiograph holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 1.2K and 2.3K respectively. Written reviews complicate that: 87% of Heart Graph's written reviews are positive against 57% of Cardiograph's, so the app with the better star average is not the one people write more warmly about.

Heart Graph ships an update every 2 weeks, Cardiograph every 5 weeks. Both last shipped on October 24, 2026.
