Sync Flow with Google Calendar and iCal
To sync your Flow calendar with either iCal or Google calendar, click the task list actions button in the top right of the screen and select calendar sync.
When the sync window appears, copy the link in the URL field.
Sync with Google Calendar
Open your Google calendar. Once open, click the drop down arrow beside Other Calendars, click Add by URL, and paste the URL you just copied from Flow.
Click add calendar to save.
You can edit the name or other details of your calendar at any time in Google’s calendar settings.
You’ll now be able to see your tasks with due dates in Google calendar and any changes you make to your tasks in Flow will be reflected on the calendar. Don’t forget that editing in Google calendar will not change your tasks in Flow.
Sync with iCal
Once you’ve copied the URL in Upcoming, open iCal. In the menubar click File>New Calendar Subscription.
Paste the URL you copied into the empty field and click Subscribe.
Now, you’ll see your Flow tasks with due dates in iCal.
To make sure iCal refreshes often to reflect changes, select Calendar>Preferences>Accounts from the menubar and set how often you want it to update.
Note that any changes you make in Flow will be reflected in iCal, but tasks edited in iCal will not change in Flow.
