Verdict

The call

The clearest difference is in-app purchases: 一键换算 at none against Smart Unit Conversion's 1. 一键换算 also leads on ads (none vs shown) and update cadence (every 4 days vs every 15 months). Smart Unit Conversion's advantage is iOS requirement (13.4 vs 15.0). On price and device support there is nothing between them.
