Verdict
The clearest difference is in-app purchases: ProfitMaster at none against かんたん利益計算's 1. ProfitMaster also leads on update cadence (every 4 days vs every 2 months). かんたん利益計算's advantage is review sentiment (70% vs 50%). On price, ads, device support and iOS requirement there is nothing between them.
