[Todoist] is a popular task management offering by Doist. You can add an existing account to BusyCal and manage all your Lists and Tasks along with all your other accounts from a single place. Changes made in BusyCal will sync to Todoist and all other devices running Todoist and vice versa.

Syncing with Todoist

To sync BusyCal with Todoist, do the following:

1. Choose BusyCal > Preferences > Accounts.
2. Click the + (plus) button to add a new account.
3. Choose Todoist from the Server Type pop-up menu, and click OK.

Known Limitations

BusyCal attempts to sync all the information retrieved from Todoist, including projects (calendars in BusyCal), task dates, notes, URL, reminders, labels etc, however the following limitations apply:

• Labels can currently only be created and managed from your Todoist account. These changes automatically sync with BusyCal.
• Some properties are not available: Attachments, Graphics, Locations, Location URLs, Private Flag.
• Location based reminders sync from Todoist → BusyCal, however you cannot currently create one from within BusyCal.
• Assigning "My Alarm", "My Notes", "My Tag" or "Contact" to a Task will not sync across multiple devices running BusyCal as Todoist does not support syncing 3rd party app meta-data.
• Rich-text notes will not sync across multiple devices running BusyCal.
• Snoozing or dismissing alarms on one device does not sync the snooze / dismissal across other devices running BusyCal.

Note that any limits that apply to your Todoist subscription plan also apply from within BusyCal. For instance, non-premium features such as adding an alarm to a task will not be available on a free account.
