# Emotor vs SMART BMS

The clearest difference is rating: Emotor at 2.9 against SMART BMS's 2.1. Emotor also leads on iOS requirement (7.1 vs 11.0). SMART BMS's advantage is update cadence (every 6 weeks vs every 4 months) and ratings volume (76 vs 14). On price, review sentiment, 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.

Emotor holds the better App Store score, 2.9 against 2.1. That said, the two scores are not equally well evidenced: SMART BMS has 76 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 19% of Emotor's written reviews are positive against 11% of SMART BMS's.

Emotor ships an update every 4 months, SMART BMS every 6 weeks. The most recent releases landed on June 10, 2026 and September 14, 2026 respectively.
