Verdict

The call

The clearest difference is in-app purchases: OpenWords at none against CapWords's 7. OpenWords also leads on review sentiment (100% vs 72%) and rating (5.0 vs 4.7). CapWords's advantage is ratings volume (633 vs 3) and update cadence (every 5 days vs every 3 weeks). On price, ads and device support there is nothing between them.
