When trying to edit calendar event. I cant seem to be able to change the calender the event is under. Would be great if this could be possible. 

Is there plans for a web version?

Off line Outlook within MS Office on my PC should be able to seamlessly synchronise with my Android phone without having to give all of my information to Google through their Calendar app(s)

Can we have an option to display the Location field in the Calendar view please? Particularly the Daily & Weekly views.

Being able to show a location-based (preferably a set location that can be changed for any given day (for example when working away or on holiday) rather than a live location) sunrise and sunset time on the calendar would be amazing.

Unfortunately the Caldav synchronisation does not work with horde.

It says no "sync token" support.

Falta data no calendário no decorrer dos dias. 

It would be great to be able to copy text from read only events (events which you cannot edit) on Android. Sometimes it is needed to copy event description or meeting link, but it is not possible to do so on the events which you cannot edit.

The app does not add all events from email, which is the one job a calendar app needs to do!

Bad experience and unfortunately paid already! 

My work week begins on Thursday. Would be nice to have the option to make that my 1st day of the week rather than only Monday or Sunday

Bei meinem Alten Kalender gabs die Möglichkeit mehrere Erinnerungen einzustellen sodass ich z.b eine Erinnerungen von einem Termin 2 Tage vorher bekomme aber auch 1 Stunde vor Termin beginn 

Das geht hier leider nicht 

Man kann nur eine Erinnerung pro Eintrag einstellen 

When I'm in the Year view of OneCalendar on Android and I tap on a month it switches to Month view, which is fine. But when I tap the (Android) Back button the app closes instead of switching back to the calendar's Year view, which is really annoying. Can you please fix this?

PLEASE add the option to email a daily agenda

Always show the actual month/ week/day in the Default View, Not the month you looked Up Last. So you can Always See today, when looking at the Widget again
