Verdict
The clearest difference is in-app purchases: Calculator Widget Pro at none against Conversion Calculator's 1. Calculator Widget Pro also leads on update cadence (every 2 days vs every 5 weeks). Conversion Calculator's advantage is review sentiment (100% vs 67%) and rating (4.8 vs 4.5). On price, ads, device support and iOS requirement there is nothing between them.
