# BMS Tool vs Blue

The clearest difference is rating: BMS Tool at 3.9 against Blue's 1.0. BMS Tool also leads on review sentiment (71% vs 50%) and ratings volume (7 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. BMS Tool 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.

BMS Tool holds the better App Store score, 3.9 against 1.0. 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 point the same way: 71% of BMS Tool's written reviews are positive against 50% of Blue's.

BMS Tool ships an update every 2 months, Blue monthly. The most recent releases landed on October 3, 2026 and October 10, 2026 respectively.
