Verdict
The clearest difference is in-app purchases: Scale Switch at none against Conversion Calculator Units's 1. Scale Switch also leads on ads (none vs shown) and rating (5.0 vs 4.7). Conversion Calculator Units's advantage is ratings volume (5K vs 1) and iOS requirement (15.0 vs 18.1). On price, update cadence and device support there is nothing between them.
