123\SmartBMS is an easy to use yet advanced, modular BMS to keep your lithium batteries in perfect condition, increasing the lifespan of the battery pack. The system measures important data like cell voltages, cell temperatures and in- and outgoing currents. It also balances all cells to the same voltage during charging. The BMS supervises the whole battery pack and has two signal relays to indicate “allow to charge” and “allow to discharge”. These signal relays can control chargers and inverters with “enable”/”disable” signals or by connecting an energy efficient power relay to the signal relay. An example is the 123\SmartRelay. Easily connect your phone to the BMS using Bluetooth to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages and temperatures. With 123\SmartBMS, your battery pack is in safe hands.

Verdict
The clearest difference is review sentiment: 123SmartBMS at 67% against BMS's 20%. 123SmartBMS also leads on ratings volume (21 vs 1). BMS's advantage is rating (5.0 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
BMS 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 20% of BMS's, so the app with the better star average is not the one people write more warmly about.
123SmartBMS ships an update monthly, BMS every 2 months. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
