Verdict
The clearest difference is ads: EZ Adder at none against Calculator HD Pro Lite's shown. EZ Adder also leads on rating (4.8 vs 4.6) and monetization model (free vs ad-supported). Calculator HD Pro Lite's advantage is ratings volume (51K vs 152). On price, update cadence, in-app purchases and device support there is nothing between them.
