# Pow Bank vs BMS

The clearest difference is review sentiment: Pow Bank at 100% against BMS's 20%. Pow Bank also leads on iOS requirement (12.0 vs 15.0). BMS's advantage is rating (5.0 vs 4.7). On price, ratings volume, update cadence and ads there is nothing between them.

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 4.7. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 100% of Pow Bank'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.

Pow Bank ships an update every 3 months, BMS every 6 weeks. The most recent releases landed on October 8, 2026 and October 25, 2026 respectively.
