# Hy vs PACEEX BMS

The clearest difference is rating: PACEEX BMS at 2.5 against Hy's 1.0. PACEEX BMS also leads on update cadence (every 5 weeks vs every 3 months) and ratings volume (6 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PACEEX BMS holds the better App Store score, 2.5 against 1.0. That said, the two scores are not equally well evidenced: PACEEX BMS has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Hy's written reviews are positive against 20% of PACEEX BMS's, so the app with the better star average is not the one people write more warmly about.

Hy ships an update every 3 months, PACEEX BMS every 5 weeks. The most recent releases landed on September 9, 2026 and July 9, 2026 respectively.
