# iCardio Workout Tracker vs Heart Graph

The clearest difference is review sentiment: Heart Graph at 87% against iCardio Workout Tracker's 63%. Heart Graph also leads on iOS requirement (15.0 vs 17.6). iCardio Workout Tracker's advantage is rating (4.8 vs 4.5). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. iCardio Workout Tracker sells 4 in-app purchases, starting at $4.99 per month and Heart Graph sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

iCardio Workout Tracker holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 3.4K and 1.2K respectively. Written reviews complicate that: 63% of iCardio Workout Tracker's written reviews are positive against 87% of Heart Graph's, so the app with the better star average is not the one people write more warmly about.
