Verdict
The clearest difference is in-app purchases: VisualMX at none against Units Converter & Calculator's 1. VisualMX also leads on ads (none vs shown). Units Converter & Calculator's advantage is update cadence (every 3 weeks vs every 4 months). On price, device support and iOS requirement there is nothing between them.
