Verdict
Compound Interest Calc and cRate Pro both sit at 4.6 stars, but that hides the real split: 90% of cRate Pro's written reviews are positive against 54% of Compound Interest Calc's. cRate Pro also leads on update cadence (every 2 months vs every 8 months) and ratings volume (148 vs 19). Compound Interest Calc's advantage is chart position (#196 vs unranked) and iOS requirement (9.0 vs 13.0). On rating, ads, in-app purchases and device support there is nothing between them.
