Verdict

The call

The clearest difference is price: FileCentral at Free against Calculator Pro's $6.99. FileCentral also leads on rating (4.8 vs 3.6) and review sentiment (88% vs 50%). Calculator Pro's advantage is update cadence (every 3 months vs every 6 months) and device support (3 vs 1). On ads, in-app purchases and iOS requirement there is nothing between them.
