Verdict
The clearest difference is rating: YellowQuest at 5.0 against Couple Diary's 4.1. YellowQuest also leads on review sentiment (100% vs 77%) and update cadence (every 2 days vs weekly). Couple Diary's advantage is ratings volume (9 vs 3) and iOS requirement (15.0 vs 26.4). On price, ads, in-app purchases and monetization model there is nothing between them.
