# BMS vs JK BMS

The clearest difference is review sentiment: JK BMS at 100% against BMS's 20%. JK BMS also leads on update cadence (weekly vs every 2 months) and ratings volume (7 vs 1). BMS's advantage is rating (5.0 vs 4.3). On price, ads, in-app purchases and monetization model 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 4.3. That said, the two scores are not equally well evidenced: JK BMS has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of BMS's written reviews are positive against 100% of JK BMS's, so the app with the better star average is not the one people write more warmly about.

BMS ships an update every 2 months, JK BMS weekly. The most recent releases landed on September 23, 2026 and October 11, 2026 respectively.
