Verdict

The call

The clearest difference is review sentiment: Calculator· at 84% against Calculator's 52%. Calculator· also leads on rating (4.9 vs 4.5). Calculator's advantage is update cadence (every 4 weeks vs every 3 months) and ratings volume (146K vs 34K). On price, ads, in-app purchases and monetization model there is nothing between them.
