# Soaak vs HeartMath

The clearest difference is review sentiment: HeartMath at 74% against Soaak's 38%. HeartMath also leads on rating (4.9 vs 4.5) and ratings volume (4.6K vs 308). Soaak's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Soaak sells 16 in-app purchases, starting at $4.99 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.

That said, the two scores are not equally well evidenced: HeartMath has 4.6K ratings behind it against 308, so its average is the more settled of the two.
