# BMS Tool vs BMS

The clearest difference is review sentiment: BMS Tool at 71% against BMS's 20%. BMS Tool also leads on ratings volume (7 vs 1). BMS's advantage is rating (5.0 vs 3.9) and in-app purchases (none vs 1). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. BMS Tool sells 1 one-off in-app purchase. BMS asks for nothing beyond the download.

BMS holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: BMS Tool has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 71% of BMS Tool'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.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 16, 2026 and September 23, 2026 respectively.
