Verdict
The clearest difference is rating: Readability at 4.6 against Number Math's 3.5. Readability also leads on review sentiment (56% vs 17%) and update cadence (fortnightly vs every 26 months). Number Math's advantage is in-app purchases (none vs 2) and iOS requirement (9.1 vs 16.4). On price, ads and device support there is nothing between them.
