Verdict
The clearest difference is in-app purchases: ARI Smart Battery at none against BMS Tool's 1. ARI Smart Battery also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). BMS Tool's advantage is device support (4 vs 2). On price and iOS requirement there is nothing between them.
