Verdict

The call

The clearest difference is ads: Calculator Pro at none against iCalc's shown. Calculator Pro also leads on rating (5.0 vs 4.6). iCalc's advantage is update cadence (every 6 days vs every 3 weeks) and ratings volume (38 vs 4). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
