World's most annoying calendar app

This is what a calendar app should be, except for the never-ending interruptions to ask for feedback and tell you about features. It's like nothing you've ever seen before, and in an app you want to use with minimal friction. I can't stand it, it's anathema to the ideal workflow. and you can't turn it off. It's the worst abuse of this power I have had to put up with in 30 years of computing. If I had to read their announcements to enable new features, I'd leave all the new features off.

Stop. Interrupting. Me.

With that out of they way, here are some of the good points:

It has a comprehensive set of online calendars you can subscribe to - things like itemised games in the Olympics and the World Cup. Perfect!

It also has a proper task manager built-in. I haven't checked yet if it's GTD-compatible, but it's better than anything else I've seen in a calendar app.

It has all the views you could want, and they're all configurable.

It has 4 standards for week numbers, which is ideal if you're using it professionally. They're turned off by default.

It has lots of shortcuts and widgets, for iPhone, iPad and Apple Watch.

You can move events from one calendar to another without issues. This should be the case with all calendar software, but it's not.

On top of all this, it can sync directly with calendar services, so you can be rid of Apple's implementation and its tendency to forget login credentials.

Now the (other) issues:

For direct connections to hosted calendars, it only supports Google and Microsoft calendars (not CalDAV), and Hotmail calendar sync doesn't work for events added from other apps (including Readdle's own Calendars 5 app). This needs some attention.

The natural language input is ok, but it can't handle a short day and date (Sun 5th July) simultaneously, which is what you might paste in, and any event name with a place name in it is going to be recognised as a place and automatically saved as the location, messing up both the event name and the location. It's not very good (and I think the logic is a decade old).

It doesn't have a lockscreen widget for tomorrow. Only for today.

Like most iOS calendar apps, you can't attach files. I don't know why this is.

You can't zoom in on the month view. You can switch view, but pinch-to-zoom with reflow text would often be better suited and it's not supported.

Love this app but home screen widgets won’t appear

I originally got this as a free upgrade and seem to recall that didn’t include the home screen widgets but I’m now on a paid subscription and the widgets still won’t appear. What to do?

Lol wrote a long review and it deleted.

TL:DR; I purchased this app years ago as a MA student even though I didn’t have the cash because I needed the functions- now I have a family and a ton of Dr. Appointments and need it more. An update keeps prompting me to update to Pro.

Even more annoying- it changed my default calendar to my Apple calendar (my spam email) and will not let me change it. The quick appointment add now is a problem- if I forget to change the calendar, my husband cannot see it on my calendar and we schedule some drs appointments a year out. I will look for another app.

best calendar app!

my fav calendar app from what i tried. the layout and interaction out does the competition. best way to keep track of your personal calendar events.

I’ve used for 4 years

Hey guys, I’m hopping on to write a review and this is my favorite calendar app. Every time I suggest something new they added such as the colors on the calendar. I remember when they barely even had all colors of the rainbow and now they have everything I love the to-do list something about this calendar. It makes me so organized in my life and you will never regret paying the $20 even in comparison to Google Calendar. I believe this calendar is the best. The only thing I hate about it is the weekly view sucks because if you put a morning routine, you’re gonna see a bunch of time blocks of that morning routine rather than the actual events of that day and I like the Google Calendar weekly review instead, but other than that, I love this app.
