Verdict
The clearest difference is rating: OCO at 4.6 against Color Sign's 4.1. OCO also leads on ratings volume (2.4K vs 12). Color Sign's advantage is update cadence (every 3 weeks vs every 5 weeks) and iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
