Verdict

The call

The clearest difference is price: Structured at Free against iCalendar's $2.99. Structured also leads on update cadence (fortnightly vs every 3 months) and ratings volume (166K vs 5.3K). iCalendar's advantage is iOS requirement (12.0 vs 18.0). On rating, review sentiment, ads and in-app purchases there is nothing between them.
