Staring in version 3.7 for iOS, you can now connect your Instagram account directly in Day One. This will pull all historical entries into a new journal called Instagram. It will include posts with multiple images and even videos.
To begin, open Day One > Settings > Instagram.
Once authenticated, your Instagram data will begin importing. We are limited in requests during a certain period of time so if you have many posts on Instagram, please be patient as this data syncs.
Multiple Instagram accounts can be added and each will have their own journal.
You can edit the name of the journal in the Journal settings or by tapping the pencil icon next to the name in the Timeline view.
If your Instagram account is set to private, then the full resolution images will not import to Day One. You will need to temporarily set it to public and then connect the account in Day One to get the full resolution images.
