Verdict

The call

The clearest difference is in-app purchases: Bioboards at none against BMS Tool's 1. Bioboards also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). BMS Tool's advantage is update cadence (every 2 months vs every 4 months). On price and device support there is nothing between them.
