# Hy vs DALY BMS

The clearest difference is rating: DALY BMS at 1.8 against Hy's 1.0. DALY BMS also leads on update cadence (weekly vs every 3 months) and ratings volume (11 vs 1). Hy's advantage is review sentiment (25% vs 10%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

DALY BMS holds the better App Store score, 1.8 against 1.0. That said, the two scores are not equally well evidenced: DALY BMS has 11 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 10% of DALY 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, DALY BMS weekly. The most recent releases landed on September 9, 2026 and September 19, 2026 respectively.
