# 极空BMS vs LANGSDOM

The clearest difference is rating: LANGSDOM at 4.0 against 极空BMS's 3.5. LANGSDOM also leads on iOS requirement (15.0 vs 17). 极空BMS's advantage is review sentiment (35% vs 0%) and ratings volume (37 vs 2). On price, update cadence, 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.

LANGSDOM holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: 极空BMS has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 35% of 极空BMS's written reviews are positive against 0% of LANGSDOM's, so the app with the better star average is not the one people write more warmly about.
