# SonicTonic vs HeartMath

The clearest difference is rating: HeartMath at 4.9 against SonicTonic's 4.5. HeartMath also leads on ratings volume (4.6K vs 11). SonicTonic's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 26.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. SonicTonic sells 13 in-app purchases, starting at $2.99 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 4.5. That said, the two scores are not equally well evidenced: HeartMath has 4.6K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 71% of SonicTonic's written reviews are positive against 74% of HeartMath's.

SonicTonic ships an update every 2 weeks, HeartMath every 3 weeks. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
