# OCO vs Color Sign

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.

Both are free to download. OCO sells 8 one-off in-app purchases and Color Sign sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OCO holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: OCO has 2.4K ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 73% of OCO's written reviews are positive against 67% of Color Sign's.

OCO ships an update every 5 weeks, Color Sign every 3 weeks. The most recent releases landed on October 17, 2026 and October 9, 2026 respectively.
