Create an app that allows notes, lists, and/or tasks to be easily created, maintained, edited, and most of all, to be more functional when achieving, completing, and crossing off list items as they become completed.

When creating tasked-based lists, I usually open up my Notes app which is slow and inefficient. It's difficult to create nested lists and delete tasks quickly and accurately.

Design an app specifically targeted for creating task-based checklists that can be maintained, edited, and completed.
