I have several sub calendars I want to be able to toggle on to see but not have visible all the time. How do I do that? Thanks!

I suffered a disk failure on my Synology NAS and I had to re-install DSM and all applications on it. From the past I know that starting synchronisation between the One Calendar app on my Android phone and Calendar Station on the NAS results in loss of all existing entries in de One Calendar app on my phone (which seems logical as a newly installed Calendar Station has no entries).

Is there a way I can export the calendar entries in the One Calendar app on my Android phone, so I can import them after starting synchronisation with Calendar Station?

What is the purpose of the "People" tab when making an appointment?  I would like to be able to pull up a person and have all of their info as well as future/past appointments scheduled.  

Hi - I'm trying to understand the functionality of the app. Can we add Caltrics to it or does the app pick up public calendars?

I'd like them by calendar type/color?  Right now it's a crap shoot - and for folks like me that are so OCD we call it CDO (because it's alphabetical that way) this is a huge stressor (it sounds crazy, i know)

I am unable to see the content of the appointment. I am able to see the time, participants etc.

In the description it shows empty.

I am using OneCalendar on android to connect to my office exchange server.

On outlook all of above work fine.

I like to use the calendar to share between windows laptop and ipad/iphone. I noticed they have different premium versions I will need. I want the premium to change the colours. If I buy both of these (windows and iOS) will the colours automatically sync also? Or will I have to manually change on each due to the premium windows not linking to premium iOS? Thanks, hope that makes sense

On my PC I keep getting this error message:

A connection with the server could not be established ---> System.Exception: The text associated with this error code could not be found.

My internet is working, I can connect to my google calendar and my microsoft exchange calendar separately, I just can't get them to sync with one calendar.  It was working very well for a long time and then about 3 weeks ago it stopped working.  

My onecalendar app is working on my ipad and my iphone just not on my PC.  I have uninstalled and reinstalled and did the

Hi, maybe you can set an option in the settings to show the current date in the app icon!!

Are you able to add Black as a colour option for calendar colours? I prefer a more minimalist color scheme. Thanks!

Could you please create a widget for the whole week? I would like to see what is going on in the week (and the next weekend… ;-)) I love your app! Thank you so much - you did a really great job!
