# Bulletproof Keto Diet vs HeartMath

The clearest difference is ratings volume: HeartMath at 4.7K against Bulletproof Keto Diet's 3. Bulletproof Keto Diet's advantage is iOS requirement (10.0 vs 26.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Bulletproof Keto Diet sells 1 one-off in-app purchase and HeartMath sells 2 in-app purchases, starting at $79.00 per year. Whichever you choose, the download price is not the number that matters.

HeartMath holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: HeartMath has 4.7K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of Bulletproof Keto Diet'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.
