OK, I am so excited about this app! Like many others have said, I have been looking for a replacement for fantastical, and this is it! It's very simple on the surface and has a lot of great features that you can customize! I am also a fan of the one time upgrade, and it seems that the developer is still keeping up with this app. I'm having a bit of a learning curve with the natural language input, but that is such a minor issue! Thank you so much for this app! Keep up the great, great work!

My Fantastical replacement! 👏🏼

Immediately after Fantastical destroyed their iOS app with V3, I started looking for a new calendar app. I (again) tried the stock Apple calendar app & it’s still just pitiful.

I’m amazed at the many great features included in this free version of Calendar 366! Not sure I want/need any of the additional features offered in the full version but will likely buy it just to support the developer.

I use month/list view & have a lot of “all day” events because I keep a rolling “to do” list on my calendar. Would like an option to turn off seeing “[all day]” on those entries. It’s already indicated by the circle around the dot (to the left of the event). And, removing that line of text would free up space & enable me to see more calendar entries in list view.

I often have a LOT of text in the “title” section (especially for my “to do” lists) & some iOS calendar apps show ALL of that info (in many lines, like a paragraph) when I click on the event - VERY helpful! Unfortunately, Cal 366 shows only a small bit of the text, in a single line. Then I have to press & hold the space bar to move the cursor & it’s really difficult to read all of it. Would love to see that changed!

Done w/Flextbit’s Fantastical!#@!

I downloaded the LE version of Calendars 366 after reading a recommendation from a former Fantastical user (who, like me, was one of the thousands of folks who owned Fantastical 2 and got burned with the disgusting Fantastical 3 update). I needed a split month/list view and Readdle hasn’t added this particular view to their Calendars app yet, so this app is working well for me. I’m getting ready to make the $6.99 investment on Calendars 366. I wish it was $4.99 (hence, 4-Stars instead of 5) but I guess it’s worth it as long as the developer respects loyal customers by not changing to a subscription-based version like the dishonest Flexbits developer did underhandedly.
