This is a very simple minimalist To Do list app.
No start dates, no end dates or reminders, just a list of items.
All the editing occurs inline. No pop-up boxes or buttons to press to make things happen. Press the + icon on the top to create your item.
To mark items as complete, tap on the rounded-square button and if find theres still a bit more to do tap on it again to mark as needing some attention.
To delete All items, tap the trash icon on the top.
