Verdict

The call

The clearest difference is ads: Temperature Converter at none against Universal Converter Pro's shown. Temperature Converter also leads on device support (3 vs 1). Universal Converter Pro's advantage is update cadence (every 5 days vs every 6 months). On price, in-app purchases and iOS requirement there is nothing between them.
