Verdict

The call

The clearest difference is ads: Calculator at none against Basic Calculator's shown. Calculator also leads on review sentiment (100% vs 76%) and rating (5.0 vs 4.8). Basic Calculator's advantage is ratings volume (3.3K vs 2) and iOS requirement (15.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
