# HeartMath vs MyCircadianApp

HeartMath and MyCircadianApp both sit at 4.9 stars, but that hides the real split: 99% of MyCircadianApp's written reviews are positive against 73% of HeartMath's. MyCircadianApp also leads on device support (3 vs 1) and iOS requirement (15.1 vs 26.0). HeartMath's advantage is ratings volume (4.6K vs 264).

Both are free to download. HeartMath sells 4 in-app purchases, starting at $39.00 per year and MyCircadianApp sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for HeartMath against 4.9 for MyCircadianApp. That said, the two scores are not equally well evidenced: HeartMath has 4.6K ratings behind it against 264, so its average is the more settled of the two.
