# One Calendar vs Cloud Calendars

The clearest difference is rating: One Calendar at 4.8 against Cloud Calendars's 4.4. One Calendar also leads on ratings volume (21K vs 9) and device support (4 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. One Calendar sells 1 one-off in-app purchase and Cloud Calendars sells 4 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

One Calendar holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: One Calendar has 21K ratings behind it against 9, so its average is the more settled of the two.

One Calendar ships an update fortnightly, Cloud Calendars every 3 weeks. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
