# SMART BMS vs RuiDeng

The clearest difference is rating: RuiDeng at 3.0 against SMART BMS's 2.1. SMART BMS's advantage is ratings volume (76 vs 2) and update cadence (every 6 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

RuiDeng holds the better App Store score, 3.0 against 2.1. That said, the two scores are not equally well evidenced: SMART BMS has 76 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 11% of SMART BMS's written reviews are positive against 0% of RuiDeng's, so the app with the better star average is not the one people write more warmly about.

SMART BMS ships an update every 6 weeks, RuiDeng every 3 months. The most recent releases landed on September 14, 2026 and September 21, 2026 respectively.
