How do sync with iCal?
You can grab our iCal feed URL from the settings page at Todoist.com (top right corner, gear icon) and this can be added to iCal on the Mac. Use the menu at the top, and Add New Subscription. This should sync with the iCal on iOS.
Thanks. What about for outlook calender ? Sent from Acompli (http://t.acompli.com/ac_sig)
You can use the same URL and subscribe to it using your Outlook calendar. You can refer to this video on how to do it. https://www.youtube.com/watch?feature=player_embedded&v=gzGubOy8GuE
Just a FYI, the settings view no longer reflects the video.
I am also having problems getting it to work with Google Calendar
Yes, our videos need to be updated, which we hope to do at some point.
That being said, what is the exact issue? When you add the URL to Google Calender, once you see the yellow message at the top, close Google Calendar, and come back a bit later, and it should try adding it in the background.
