You can import your tasks from Wunderlist, Asana, and from Microsoft To Do.

To import them, tap or click "Import from other apps" and choose the app you want. 

For Wunderlist, you will first need to download the ZIP file of your data from For Microsoft To Do you will need to log in and approve access.

We do not have an import for Todoist yet, but we will have one in the future!
