Verdict
The clearest difference is price: FriedrichLink at Free against Density Converter's $1.99. FriedrichLink also leads on update cadence (every 5 weeks vs every 38 months). Density Converter's advantage is device support (3 vs 1) and iOS requirement (13.4 vs 17.0). On ads and in-app purchases there is nothing between them.
