# KeyCard BBM vs Blue

The clearest difference is rating: KeyCard BBM at 4.7 against Blue's 1.0. KeyCard BBM also leads on review sentiment (84% vs 50%) and ratings volume (1.6K vs 1). Blue's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. KeyCard BBM sells 1 one-off in-app purchase and Blue sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

KeyCard BBM holds the better App Store score, 4.7 against 1.0. 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 point the same way: 84% of KeyCard BBM's written reviews are positive against 50% of Blue's.

KeyCard BBM ships an update every 2 weeks, Blue monthly. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
