Verdict
The clearest difference is in-app purchases: Complex Number Cruncher at none against Calculator #'s 6. Complex Number Cruncher also leads on ads (none vs shown) and iOS requirement (10.3 vs 12.1). Calculator #'s advantage is ratings volume (36K vs 4) and rating (4.6 vs 4.3). On price, update cadence and device support there is nothing between them.
