# 123SmartBMS vs EV Battery

The clearest difference is review sentiment: 123SmartBMS at 67% against EV Battery's 0%. 123SmartBMS also leads on ratings volume (21 vs 1). EV Battery's advantage is rating (5.0 vs 4.5) and iOS requirement (9.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

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

EV Battery 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 0% of EV Battery's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 7, 2026 and October 16, 2026 respectively.
