# RuiDeng vs DALY BMS

The clearest difference is rating: RuiDeng at 3.0 against DALY BMS's 1.8. DALY BMS's advantage is update cadence (weekly vs every 3 months) and review sentiment (10% vs 0%). 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.

RuiDeng holds the better App Store score, 3.0 against 1.8. That said, the two scores are not equally well evidenced: DALY BMS has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of RuiDeng'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.

RuiDeng ships an update every 3 months, DALY BMS weekly. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
