# Harmoni vs HeartMath

The clearest difference is rating: HeartMath at 4.9 against Harmoni's 3.0. HeartMath also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (4.7K vs 1). Harmoni's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Harmoni sells 7 in-app purchases, starting at $11.99 per month and HeartMath sells 4 in-app purchases, starting at $39.00 per year. Whichever you choose, the download price is not the number that matters.

HeartMath holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: HeartMath has 4.7K ratings behind it against 1, so its average is the more settled of the two.

Harmoni ships an update every 5 months, HeartMath every 3 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
