# 宇扬星蓝牙助手 vs BAT

The clearest difference is rating: 宇扬星蓝牙助手 at 3.5 against BAT's 3.0. 宇扬星蓝牙助手 also leads on iOS requirement (7.0 vs 12.0). BAT's advantage is update cadence (every 3 weeks vs every 14 months) and review sentiment (24% vs 0%). On price, ads, in-app purchases and device support there is nothing between them.

宇扬星蓝牙助手 holds the better App Store score, 3.5 against 3.0. That said, the two scores are not equally well evidenced: BAT 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 24% of BAT's, so the app with the better star average is not the one people write more warmly about.
