# HeartMath vs Lumaflex

The clearest difference is rating: HeartMath at 4.9 against Lumaflex's 4.0. HeartMath also leads on ratings volume (4.8K vs 4). Lumaflex's advantage is in-app purchases (none vs 2) and update cadence (weekly vs every 3 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. HeartMath sells 2 in-app purchases, starting at $79.00 per year. Lumaflex asks for nothing beyond the download.

HeartMath holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: HeartMath has 4.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 74% of HeartMath's written reviews are positive against 75% of Lumaflex's, so the app with the better star average is not the one people write more warmly about.

HeartMath ships an update every 3 weeks, Lumaflex weekly. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
