Verdict
The clearest difference is price: Unit Converter at Free against Konvert's $1.99. Unit Converter also leads on review sentiment (100% vs 79%) and update cadence (weekly vs monthly). Konvert's advantage is in-app purchases (none vs 1) and ads (none vs shown). On rating and device support there is nothing between them.
