Verdict
The clearest difference is in-app purchases: ReadVortex at none against My Units Converter Pro's 2. ReadVortex also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). My Units Converter Pro's advantage is update cadence (every 2 months vs every 6 months). On price and device support there is nothing between them.
