Verdict

The call

Calculator⁼ and iCalc both sit at 4.6 stars, but that hides the real split: 100% of iCalc's written reviews are positive against 36% of Calculator⁼'s. iCalc also leads on update cadence (every 6 days vs monthly) and iOS requirement (12.0 vs 15.0). Calculator⁼'s advantage is ratings volume (358K vs 38). On price, rating, ads and in-app purchases there is nothing between them.
