# Bluetooth DMM vs SMART BMS

The clearest difference is rating: Bluetooth DMM at 2.5 against SMART BMS's 2.2. Bluetooth DMM also leads on update cadence (every 2 weeks vs every 6 weeks) and iOS requirement (9.0 vs 11.0). SMART BMS's advantage is review sentiment (17% vs 0%) and ratings volume (78 vs 4). 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 DMM holds the better App Store score, 2.5 against 2.2. That said, the two scores are not equally well evidenced: SMART BMS has 78 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of Bluetooth DMM'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.

Bluetooth DMM ships an update every 2 weeks, SMART BMS every 6 weeks. The most recent releases landed on October 12, 2026 and October 22, 2026 respectively.
