# 123SmartBMS vs Bluetooth Li

The clearest difference is rating: Bluetooth Li at 5.0 against 123SmartBMS's 4.5. Bluetooth Li also leads on iOS requirement (12.0 vs 16.0). 123SmartBMS's advantage is update cadence (monthly vs every 5 months) and review sentiment (67% vs 50%). 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.

Bluetooth Li holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: 123SmartBMS has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of 123SmartBMS's written reviews are positive against 50% of Bluetooth Li's, so the app with the better star average is not the one people write more warmly about.

123SmartBMS ships an update monthly, Bluetooth Li every 5 months. The most recent releases landed on October 7, 2026 and September 29, 2026 respectively.
