Verdict
The clearest difference is rating: Cupla at 4.7 against World Day's 3.3. Cupla also leads on review sentiment (73% vs 38%) and update cadence (every 9 days vs every 5 months). World Day's advantage is device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
