Verdict
The clearest difference is ads: Sparkling Day at none against Catendar's shown. Sparkling Day also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.0). Catendar's advantage is update cadence (every 5 days vs fortnightly). On price and in-app purchases there is nothing between them.
