# KeyCard BBM vs BMS

The clearest difference is review sentiment: KeyCard BBM at 84% against BMS's 20%. KeyCard BBM also leads on ratings volume (1.6K vs 1) and update cadence (every 4 weeks vs every 2 months). BMS's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

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

BMS holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: KeyCard BBM has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 84% of KeyCard BBM'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.

KeyCard BBM ships an update every 4 weeks, BMS every 2 months. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
