The clearest difference is update cadence: Calculator⁼ at monthly against Caculator's every 10 months. Calculator⁼ also leads on ratings volume (359K vs 2). Caculator's advantage is rating (5.0 vs 4.6) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
