# iCalendar vs Duel Connect

The clearest difference is price: Duel Connect at Free against iCalendar's $2.99. Duel Connect also leads on review sentiment (100% vs 71%) and iOS requirement (13.0 vs 15.6). iCalendar's advantage is rating (4.7 vs 3.7) and ads (none vs shown). On update cadence, in-app purchases and monetization model there is nothing between them.

Duel Connect is free to download; iCalendar costs $2.99 up front. iCalendar sells 10 in-app purchases, starting at $1.99 per year and Duel Connect sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iCalendar holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: iCalendar has 5.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 71% of iCalendar's written reviews are positive against 100% of Duel Connect's, so the app with the better star average is not the one people write more warmly about.

iCalendar ships an update every 3 months, Duel Connect every 2 months. The most recent releases landed on October 22, 2026 and October 7, 2026 respectively.
