We’ve no plans to implement anything OSX specific however if you use a cloud service with your Mac calendar (Hotmail/Yahoo/Google etc) you can synchronise this with your phone

As Windows Phone is now discontinued we won’t be adding any new features.

The Windows Phone app is no longer actively developed. We’ll use your feedback for future version planning.

Duplicate idea

The Windows Phone app is no longer in development. But we will use your feedback for future planning

Our app doesn’t enforce any feedback survey or anything similar.

Because the only way of writing appointments to the calendar is through the edit appointment dialog we can’t perform any kind of automatic sync to the phone calendar. This is a platform limitation

Other than supporting .ics attachments we can’t hook into the email application to get notified in this way.

The capabilities on Windows Phone do not allow inserting recurring events into the device calendar programmatically so this is not currently possible to support

You can setup the built in Calendar application to synchronise with an Exchange ActiveSync source so there is no need for this functionality.

Now that Outlook Mail and Calendar on Windows 10 natively supports ics imports we won’t be adding new features.

Windows Phone 8 offers no way to programmatically specify recurrence schedules so this is not possible. We’ll re-evaluate if the platform gets updated
