# Progressive Muscle Relaxation. vs HeartMath

The clearest difference is price: HeartMath at Free against Progressive Muscle Relaxation.'s $6.99. HeartMath also leads on ratings volume (4.8K vs 12) and update cadence (every 3 weeks vs every 3 months). Progressive Muscle Relaxation.'s advantage is in-app purchases (none vs 2) and review sentiment (92% vs 74%). On ads and device support there is nothing between them.

HeartMath is free to download; Progressive Muscle Relaxation. costs $6.99 up front. HeartMath sells 2 in-app purchases, starting at $79.00 per year. Progressive Muscle Relaxation. asks for nothing beyond the download.

HeartMath holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: HeartMath has 4.8K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 92% of Progressive Muscle Relaxation.'s written reviews are positive against 74% of HeartMath's, so the app with the better star average is not the one people write more warmly about.

Progressive Muscle Relaxation. ships an update every 3 months, HeartMath every 3 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
