Verdict

The call

The clearest difference is in-app purchases: Correct Change at none against iCodex's 1. Correct Change also leads on iOS requirement (12.0 vs 17.6). iCodex's advantage is update cadence (every 3 weeks vs every 7 months). On price, review sentiment, ads and device support there is nothing between them.
