Verdict
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.
