How do I save / backup my iOS / iPhone notes?
Notes from the stock iOS Notes app can be synced, backed up and viewed on a computer. If you take notes with an iPhone, iPad or iPod touch, these are included in the default iTunes and iCloud backups. To view and edit notes on your computer, you must sync Notes with iTunes.
From the iTunes Info tab, select the checkbox next to Other -> Sync notes.
After you sync or backup the iOS device, your notes will appear in the OS X Mail app or in Outlook on a Windows machine.
Alternatively, you can open a note and tap the share button in the lower left corner. This will provide options to Message, Email, Copy or Print the note currently being viewed.
