Gallery Quick-Add for Subtasks
4.Do also lets you add multiple subtasks at once by importing from one or more pictures in your gallery.
Tap the Subtask Gallery Quick-Add button.
Choose the pictures containing the subtasks you want to import.
Tap the done button.
4.Do will parse your pictures into subtasks. From there you can:
Tap a subtask to edit it.
Swipe a subtask to remove it.
Tap the add button to add all parsed subtasks to your task.
Note: 4.Do will parse all text it can find in the pictures you import, so choose carefully.
