Verdict

The call

The clearest difference is rating: CHMate at 3.9 against Reader+'s 2.6. CHMate also leads on review sentiment (55% vs 18%) and update cadence (every 2 weeks vs every 3 months). Reader+'s advantage is iOS requirement (9.0 vs 26.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
