Verdict
The clearest difference is ads: DDays at none against Ditto's shown. DDays also leads on review sentiment (100% vs 67%) and monetization model (free vs ad-supported). Ditto's advantage is update cadence (every 3 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
