Verdict
The clearest difference is in-app purchases: CalendarDuo at none against Dynamic Calendar's 1. CalendarDuo also leads on review sentiment (50% vs 23%) and iOS requirement (15.1 vs 17.0). Dynamic Calendar's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). On price and device support there is nothing between them.
