Add detailed sketches from within the app
One of the most fun additions to Notes is a fully fleshed-out sketchbook feature. You can scrawl colorful doodles as part of any note -- which is useful for designers or artists who're feeling inspired, but also for us less talented folk who need to illustrate an idea to coworkers in an email.
Tap the squiggly line along the bottom rail of any existing note and it'll generate a blank canvas for you to draw upon, complete with a full set of tools and utensils including a pencil, marker, pen, eraser, ruler, and color selector. Once you're finished drawing, tap Done and it'll drop your sketch in line with whatever was in the note before you started sketching. (For all you old-school iPhoners out there, this feature only works on the iPhone 5 or newer.)
Add maps and links with just a few taps
Let’s say, for instance, you're using Notes to brainstorm an itinerary for a big summer trip. You can save important info from around the web in a note by embedding links and maps you come across on other built-in apps like Safari or Maps. Simply pull up the share tools while on the particular page you're interested in, tap the Notes icon, and select the note it belongs in.
