# BMS Tool vs LIONTRON Multi

The clearest difference is review sentiment: BMS Tool at 71% against LIONTRON Multi's 27%. BMS Tool also leads on ratings volume (7 vs 1). LIONTRON Multi's advantage is rating (5.0 vs 3.9) and in-app purchases (none vs 1). On price and device support there is nothing between them.

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

LIONTRON Multi 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 27% of LIONTRON Multi's, so the app with the better star average is not the one people write more warmly about.

BMS Tool ships an update every 2 months, LIONTRON Multi every 3 weeks. The most recent releases landed on October 3, 2026 and October 7, 2026 respectively.
