Verdict
The clearest difference is in-app purchases: Box Builder at none against Bassport Pro's 1. Box Builder also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.0). Bassport Pro's advantage is update cadence (every 5 days vs every 7 months). On price and device support there is nothing between them.
