# 宇扬星蓝牙助手 vs SMART BMS

The clearest difference is rating: 宇扬星蓝牙助手 at 3.5 against SMART BMS's 2.2. 宇扬星蓝牙助手 also leads on iOS requirement (7.0 vs 11.0). SMART BMS's advantage is update cadence (every 6 weeks vs every 14 months) and ratings volume (78 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

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

宇扬星蓝牙助手 holds the better App Store score, 3.5 against 2.2. That said, the two scores are not equally well evidenced: SMART BMS has 78 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of 宇扬星蓝牙助手's written reviews are positive against 17% of SMART BMS's, so the app with the better star average is not the one people write more warmly about.

宇扬星蓝牙助手 ships an update every 14 months, SMART BMS every 6 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
