Verdict
The clearest difference is in-app purchases: Battery Pack Assistant at none against BMS Tool's 1. Battery Pack Assistant also leads on ads (none vs shown) and iOS requirement (9.0 vs 15.2). BMS Tool's advantage is update cadence (every 2 months vs every 5 months). On price and device support there is nothing between them.
