# Calendars vs Sorted³

The clearest difference is ratings volume: Calendars at 122K against Sorted³'s 4.1K. Calendars also leads on chart position (#103 vs unranked). Sorted³'s advantage is review sentiment (73% vs 55%) and iOS requirement (15.6 vs 18.2). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Calendars sells 18 in-app purchases, starting at $3.99 per month and Sorted³ sells 11 one-off in-app purchases. 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 Calendars against 4.7 for Sorted³. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 4.1K, so its average is the more settled of the two. Written reviews are what separate them: 55% of Calendars's written reviews are positive against 73% of Sorted³'s.

Calendars ships an update every 11 days, Sorted³ every 3 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
