Verdict
The clearest difference is ads: EZ Adder at none against Calculator's shown. EZ Adder also leads on update cadence (every 2 months vs every 13 months) and monetization model (free vs ad-supported). Calculator's advantage is ratings volume (910 vs 152). On price, rating, review sentiment and in-app purchases there is nothing between them.
