About the Tasks app
With the Tasks by BlackBerry app, you can stay organized by creating a list of tasks with due dates and reminders.
You can save your tasks locally on your device, or synchronize them with an account that uses Microsoft Exchange ActiveSync, such as Microsoft Outlook. To add an account to your device, in the Tasks app, tap > Add account, and then complete the instructions on the screen.
If you want to import tasks from a BlackBerry device, you can use the BlackBerry Content Transfer app. For more information, see the help for BlackBerry Content Transfer.
