# B100X vs デビルハーモニクス

The clearest difference is in-app purchases: デビルハーモニクス at none against B100X's 10. デビルハーモニクス also leads on update cadence (every 2 days vs every 10 days) and iOS requirement (11.0 vs 15.0). B100X's advantage is ratings volume (220 vs 4) and review sentiment (84% vs 70%). On price, rating, ads and device support there is nothing between them.

Both are free to download. B100X sells 10 in-app purchases, starting at $2.99 per month. デビルハーモニクス asks for nothing beyond the download.

デビルハーモニクス holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: B100X has 220 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 84% of B100X's written reviews are positive against 70% of デビルハーモニクス's, so the app with the better star average is not the one people write more warmly about.

B100X ships an update every 10 days, デビルハーモニクス every 2 days. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
