# Calendars vs 1day Schedule

The clearest difference is ads: Calendars at none against 1day Schedule's shown. Calendars also leads on update cadence (weekly vs every 2 months) and ratings volume (122K vs 4). 1day Schedule's advantage is review sentiment (75% vs 56%) and iOS requirement (15.6 vs 18.2). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calendars sells 18 in-app purchases, starting at $3.99 per month and 1day Schedule sells 1 one-off in-app purchase. 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 4.8 for 1day Schedule. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 56% of Calendars's written reviews are positive against 75% of 1day Schedule's.

Calendars ships an update weekly, 1day Schedule every 2 months. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
