Verdict
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.

Structured is free to download; iCalendar costs $2.99 up front. iCalendar sells 10 in-app purchases, starting at $1.99 per year and Structured sells 12 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for iCalendar against 4.8 for Structured. That said, the two scores are not equally well evidenced: Structured has 166K ratings behind it against 5.3K, so its average is the more settled of the two. Written reviews are what separate them: 72% of iCalendar's written reviews are positive against 78% of Structured's.
iCalendar ships an update every 3 months, Structured fortnightly. Both last shipped on September 25, 2026.
