A hidden gem

How does this calendar not have more customers?? The interface is brilliant and versatile; the list view in month, week, OR day mode is what I’ve needed for YEARS. The price is right. The privacy policy is non-invasive. Unless I’m missing something, this calendar app is a masterpiece.

Like many others, I’ve been on the search for a new calendar app after another developer decided to remove calendar features that we had already paid for, only to lock them into a subscription tier. I have looked closely at about 2 dozen calendar apps within the last few days, and Calendar 366 is far and away the best of the ones I’ve seen. It’s early and maybe I’ll discover bugs or glitches down the road, but the UI blows me away and this developer seems to do things the right way; I’ll roll the dice on a company like that. I tried the free version first and have just upgraded to pay in full. Here’s hoping that this app is the long term answer for me and anyone else looking for an alternative calendar solution.

Better Than Fantastical, Thanks

This is a great calendar app I think and I'm always happy to support developers and companies that are ethical and who don't use greedy subscriptions for their applications. Please don't ever turn into one of the soulless creeps who use subscriptions with their app and ruin this calendar.

I would guess you've gained quite a few new customers that came from the now dead Fantastical app. Which, many of us are very loyal customers to developers and good quality apps that keep their apps premium like we bought them in the first place, unlike Fantastical. So, please don't betray our trust like that scummy developer did and please keep this calendar app premium. And, many thanks for this great application and for being an upstanding developer it seems. Being ethical and moral with how you sell your app, really goes a long way towards engendering trust in your customers. Thanks, again, and God bless.

Just keeps getting better!

What was already a great app has been made even better with version 1.6.0. Both fixes (e.g. search function) and new features (e.g. font sizing) have been implemented. The developer listens and delivers. Highly recommended still.

Old review: With this latest update the developer has provided enhanced capabilities and even a few fixes. This is an excellent example of a developer listening to customer feedback and then coming through. For my money Calendar 366 is the best choice. Highly recommended.

Old review: Yes, Calendar 366 is genuinely a fine agenda and reminder app. However, this is eclipsed by the developer’s dedication to the customer. When I reported a problem with the location search feature the developer listened, agreed that there was indeed a bug and produced a fix in less than forty-eight hours! Now Calendar 366 is feature packed and flawlessly executed. Highly recommended without hesitation.
