# RdPower vs SMART BMS

The clearest difference is rating: SMART BMS at 2.1 against RdPower's 1.7. SMART BMS also leads on ratings volume (76 vs 13).

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

SMART BMS holds the better App Store score, 2.1 against 1.7. That said, the two scores are not equally well evidenced: SMART BMS has 76 ratings behind it against 13, so its average is the more settled of the two. Written reviews split almost evenly too, at 17% and 17% positive.
