Will gladly pay another 1 TIME fee for that ### 5/5 — Thanks for updating app for 2026! *2026-01-01, version 2.11.2* I love this app because it allows you to share .ics calendar appointments via email with other users, without having to use iCloud. It also has the best combined monthly/daily-list view too, and no subscription is required! Note for developer: Realizing it’s a lot of work to keep updating an app without receiving subscription fees, I want to say thanks. In the future I’m sure they’re many existing users that would gladly pay another one-time fee for important updates. :) ### 1/5 — PLEASE UPDATE FOR iOS 26!!! *2025-11-12, version 2.11.1* Used to be a great 5–Star app, which I’ve been using for years now. However, it desperately needs to be updated for iOS 26 because I’m having serious problems with unwanted time zone shifts on appointments and lack of liquid display support. I put in a support request to the developer, but I never received a response back, so that’s why I posted this downgraded review. Please update this app so I can change my rating back to 5-Stars. Thanks! ### 2/5 — Become buggy. *2025-11-05, version 2.11.1* Update: Over time bugs emerging. Reported to developer but no fixes, no reply so maybe now abandoned? Bugs are getting annoying. Reduced rating. I've been through quite a few calendar apps and always had to switch back to Apple's built in calendar. I don't find Apple's iOS calendar very useful (poor use of limited screen space, limited view options, etc.) Calendar 366 ticks all the "Pros" and none of the "Cons". 1. It works (nor all paid for competitors do) 2. Battery and network efficient. 3. Very customisable views - easy to tweak. 4. Good use of limited screen space on iPhone 5. Lots of different views etc. ### 1/5 — Meh *2025-09-19, version 2.11.1* I purchased Calendar 366 after Fantastical went subscription. Initially it was a good choice. However, in the ensuing years, the developer has become less and less responsive, and innovation and support have waned. Moving on to another calendar tool. ### 3/5 — Include vertical scroll and weather *2025-09-04, version 2.11.1* All I need now Include vertical scroll and weather to give this a 5star rating ### 5/5 — Awesome Calendar *2025-07-30, version 2.11.1* The app is full featured but simple to use. I also like that it doesn’t require a subscription or an account. It’s also a great app for privacy oriented users as there is no data collection. I’ve emailed customer service a few times with questions and each time they got back to me in a day. ### 4/5 — Add weather and it would be perfect *2025-05-12, version 2.11.1* Add weather like fantastical to make it the perfect app ### 5/5 — Very grateful for this Calendar app *2025-05-08, version 2.11.1* I have used Calendar 366 for a number of years now on both my iPhone and Mac. Maintained by a single developer who gets back very quickly if you write with questions, and/or requests. Go searching through the settings, it is more powerful than on first site. If you want to add more power to Apple’s Calendar app, but don’t need all the bells and whistles of some other apps, I highly recommend Calendar 366. ### 1/5 — App is broken *2025-04-09, version 2.11.1* When I try to edit an existing event, access denied message pops up. ## Frequently asked questions about Calendar 366 ### What does Calendar 366 do?
