# Calendars vs Penguin Planner

The clearest difference is review sentiment: Penguin Planner at 100% against Calendars's 56%. Penguin Planner also leads on rating (5.0 vs 4.7) and iOS requirement (15.6 vs 18.2). Calendars's advantage is ratings volume (123K vs 1) and chart position (#134 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calendars sells 10 in-app purchases, starting at $3.99 per month and Penguin Planner sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Penguin Planner 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 1, 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 100% of Penguin Planner's.

Calendars ships an update weekly, Penguin Planner fortnightly. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
