Verdict
The clearest difference is rating: Arithmetic Wiz at 2.0 against Pearl Diver HD's 1.5. Arithmetic Wiz also leads on update cadence (every 4 months vs every 20 months) and iOS requirement (15.0 vs 17.6). Pearl Diver HD's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment, ratings volume and device support there is nothing between them.
