# 极空BMS vs Balance BMS

The clearest difference is rating: Balance BMS at 4.0 against 极空BMS's 3.4. Balance BMS also leads on iOS requirement (12.0 vs 17). 极空BMS's advantage is ratings volume (38 vs 6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Balance BMS holds the better App Store score, 4.0 against 3.4. That said, the two scores are not equally well evidenced: 极空BMS has 38 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 34% of 极空BMS's written reviews are positive against 31% of Balance BMS's, so the app with the better star average is not the one people write more warmly about.

极空BMS ships an update every 3 weeks, Balance BMS every 6 weeks. The most recent releases landed on October 23, 2026 and October 21, 2026 respectively.
