Verdict

The call

The clearest difference is ratings volume: Calculator₊ at 1.7M against The Simple Calculator's 171. Calculator₊ also leads on chart position (#111 vs unranked) and device support (5 vs 3). The Simple Calculator's advantage is review sentiment (77% vs 63%) and update cadence (weekly vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.
