Verdict
The clearest difference is monetization model: OffOf at free against Color Date's paid. OffOf also leads on review sentiment (61% vs 33%) and device support (5 vs 2). Color Date's advantage is update cadence (fortnightly vs every 59 months). On price, ads, in-app purchases and iOS requirement there is nothing between them.
