Verdict
The clearest difference is review sentiment: Datum at 100% against Color Date's 33%. Datum also leads on device support (5 vs 2). Color Date's advantage is update cadence (fortnightly vs every 3 months) and price ($0.99 vs $1.99). On ads, in-app purchases, monetization model and iOS requirement there is nothing between them.
