# OnPurposeChiro vs HeartMath

The clearest difference is in-app purchases: OnPurposeChiro at none against HeartMath's 5. OnPurposeChiro also leads on device support (3 vs 1) and iOS requirement (11.2 vs 26.0). HeartMath's advantage is ratings volume (4.6K vs 1) and update cadence (every 3 weeks vs every 3 months). On price, rating and ads there is nothing between them.

Both are free to download. HeartMath sells 4 in-app purchases, starting at $39.00 per year. OnPurposeChiro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for OnPurposeChiro against 4.9 for HeartMath. That said, the two scores are not equally well evidenced: HeartMath has 4.6K ratings behind it against 1, so its average is the more settled of the two.

OnPurposeChiro ships an update every 3 months, HeartMath every 3 weeks. The most recent releases landed on June 11, 2026 and September 28, 2026 respectively.
