Verdict
The clearest difference is ads: FEUrea Calculator at none against Calculation's shown. FEUrea Calculator also leads on device support (3 vs 1) and iOS requirement (12.1 vs 16.0). Calculation's advantage is update cadence (every 2 months vs every 5 months). On price and in-app purchases there is nothing between them.
