Verdict
The clearest difference is ads: CarExpense at none against Dilution Calculator's shown. CarExpense also leads on update cadence (every 9 days vs every 6 weeks). Dilution Calculator's advantage is iOS requirement (15.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
