# Calendars vs To

The clearest difference is review sentiment: To at 94% against Calendars's 56%. To also leads on rating (5.0 vs 4.7) and iOS requirement (15.0 vs 18.2). Calendars's advantage is ads (none vs shown) and ratings volume (123K vs 29). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Calendars sells 10 in-app purchases, starting at $3.99 per month and To sells 10 in-app purchases, starting at $4.90 per month. Whichever you choose, the download price is not the number that matters.

To holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Calendars has 123K ratings behind it against 29, so its average is the more settled of the two. Written reviews point the same way: 56% of Calendars's written reviews are positive against 94% of To's.

Calendars ships an update weekly, To fortnightly. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
