Verdict
The clearest difference is in-app purchases: DDays at none against DAYBOX's 2. DDays also leads on ads (none vs shown) and review sentiment (100% vs 76%). DAYBOX's advantage is update cadence (every 5 days vs every 2 weeks) and iOS requirement (15.6 vs 17.0). On price and device support there is nothing between them.
