Verdict
The clearest difference is rating: RMSA at 5.0 against Calculator Plus's 4.5. RMSA also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Calculator Plus's advantage is ratings volume (2.2K vs 1) and update cadence (every 2 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
