# BAT vs BMS

The clearest difference is rating: BMS at 5.0 against BAT's 3.2. BAT's advantage is ratings volume (61 vs 1) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, 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.

BMS holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: BAT has 61 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 24% of BAT'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.

BAT ships an update every 3 weeks, BMS every 2 months. The most recent releases landed on October 12, 2026 and September 23, 2026 respectively.
