# HeartMath vs Flex Your Feminine

The clearest difference is review sentiment: Flex Your Feminine at 100% against HeartMath's 74%. Flex Your Feminine also leads on iOS requirement (15.0 vs 26.0). HeartMath's advantage is ratings volume (4.7K vs 9) and rating (4.9 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. HeartMath sells 4 in-app purchases, starting at $39.00 per year and Flex Your Feminine sells 5 in-app purchases, starting at $45.90 per month. Whichever you choose, the download price is not the number that matters.

HeartMath holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: HeartMath has 4.7K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 74% of HeartMath's written reviews are positive against 100% of Flex Your Feminine'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, Flex Your Feminine every 2 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
