Most of the new Notes features in iOS 9.3 are found within the app itself, but the ability to sort notes by date created, date modified, or alphabetically is found in the Settings app. Follow these instructions to sort the notes in your Notes app on your iPad:
- Open your Settings app from the Home screen.
- Tap the Notes panel.
- Tap the Sort Notes By panel.
- Select Date Edited, Date Created or Title.
You can create a checklist or password protect your notes inside the Notes app.
