I love that this app allows for vertical scrolling that allows you to stop mid month, partially seeing the previous/following month. My one 'wish list' item is for the calendar to indicate major holidays. Update: Thanks for that reply, Tapir! I just learned how to add Holidays! That was well worth the one-time $2.49!

Best calendar for me, especially because of great week view. I've used it for 12+ years. Tried Google, Samsung... both good, but I need the A calendar week view. Also, A is simple to use, and doesn't require sign in, personal info, etc. I've tried others here and there, and they weren't right for me. Thanks A calendar for keeping it simple and user friendly.

Update 3/29/25 Doesn't sync new events on my Samsung S24, even when I manually sync, but syncing still works on my S22. I have to wait for some unknown something to get it to sync. As you can imagine, this renders it useless. Love the birthday photos, the calendar color choices (I have 6 different calendars on my device and it handles that beautifully).
