# BatteryMonitorBL vs SRNE

The clearest difference is rating: SRNE at 4.2 against BatteryMonitorBL's 2.3. SRNE also leads on update cadence (fortnightly vs every 6 months). BatteryMonitorBL's advantage is review sentiment (50% vs 40%). On price, ratings volume, 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.

SRNE holds the better App Store score, 4.2 against 2.3. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 50% of BatteryMonitorBL's written reviews are positive against 40% of SRNE's, so the app with the better star average is not the one people write more warmly about.

BatteryMonitorBL ships an update every 6 months, SRNE fortnightly. The most recent releases landed on September 27, 2026 and October 11, 2026 respectively.
