# SMART BMS vs Bluetooth Li

The clearest difference is rating: Bluetooth Li at 5.0 against SMART BMS's 2.1. Bluetooth Li also leads on review sentiment (50% vs 17%). SMART BMS's advantage is ratings volume (76 vs 1) and update cadence (every 6 weeks vs every 5 months). 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 2.1. That said, the two scores are not equally well evidenced: SMART BMS has 76 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 17% of SMART BMS's written reviews are positive against 50% of Bluetooth Li's.

SMART BMS ships an update every 6 weeks, Bluetooth Li every 5 months. The most recent releases landed on October 16, 2026 and October 12, 2026 respectively.
