Create Checklists
There are a lot of advanced formatting features that can be found in Notes now, and one of the most useful is that ability to create checklists in your notes. A simple tap on the checkbox button at the bottom of the screen when creating or editing a note will add a checklist. This can also be anywhere in the body of your note, and combined with other text, so you could easily tack a to-do list onto a note describing travel plans, or a list of ingredients to buy for a recipe that you’ve saved.
Once you’ve created a checklist, you can simply tap on the empty circles to check items off, even when you’re not in editing mode. Unfortunately, that’s about as sophisticated as it gets right now — there’s no drag-and-drop reordering of checklists, nor a way to hide those items that have been checked off. However, it’s still pretty handy for dealing with very simple lists, and if you require a bit more, there’s always Apple’s Reminders app.
