Verdict

The call

The clearest difference is ads: Calculator M+ at none against Basic Calculator's shown. Calculator M+ also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (12.0 vs 15.0). Basic Calculator's advantage is rating (4.8 vs 4.5) and ratings volume (3.2K vs 110). On price, in-app purchases, monetization model and device support there is nothing between them.
