I love the app, but I can't use it without event templates. I have irregularly recurring appointments, and I don't want to type in all the details every time. I know that I can copy an event, but that would require scrolling back to find the event that I want to copy. Several calendar apps have a template back, such as Business Calendar 2. The devs should look there if they don't know what I'm talking about.

We have 2 solutions for this: either use our multi-copy feature or auto-completion. I know what a template is, and I strongly believe that in most cases our solutions are better. Please send us details about your use case to, and we'll have a look at it.

There are just so many clever things incorporated in this calendar's design: Excellent customization features, like tweaks for how to display in each time span; being able to set the visible time range, yet the calendar will prudently show it with a 30 min buffer space before and after; the little week overview in the corner of the daily (rather than having a daily that's just awkwardly wide); notification customization - I'm out of space. It's AWESOME. I cannot return to other calendars.

My only complaint is recently I now would have to pay for extra colors when they've been available to me all these years. Most of my recurring events are in colors that are no longer available to me. Since I put up with more frequent pop up ads than what used to be on here, I think now charging just for extra colors is stupid, especially when it's something you offered free for many years. I didn' circumvented anything. I don't know how to do that. The colors were always just available to me.

Proprietary colors (added with version 2) have always been a plus feature, but it seems like there were ways to circumvent the paywall. Generally, I'd recommend against using proprietary colors - there's almost always a better solution. Mostly everyone having this problem is using the Samsung cloud calendar, which I'd strongly advice against using.
