Verdict
The clearest difference is price: Convertall at Free against Unit Converter's $5.99. Convertall also leads on update cadence (every 5 weeks vs every 9 months). Unit Converter's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support and iOS requirement there is nothing between them.
