With Notes, you can pin your top notes, sketch ideas, create checklists, scan and sign documents, and add attachments — like photos, videos, or web links. And with iCloud, you can keep your notes updated across all your devices.
Pin a Note
Pin your favorite or most important notes to make them easier to find. To pin a note, swipe right over the note, then release. Or go to the note, tap the More button, then tap the Pin button. To unpin a note, swipe right over the note again.
Format a Note
When you're in a note, tap the table button or the formatting button to add a table, title, heading, or bulleted list. You can also touch and hold to quickly open a list of formatting options.
Add an Attachment
To add something from another app, like a location or website, tap the Share button in the app that you want to share from. Tap the Notes app, then select the note that you want to add an attachment to, then tap Save.
Add a Photo or Video
To add a photo or video, tap in a note, then tap the Camera button. Tap Take Photo or Video to create a new photo or video, or Choose Photo or Video to add an existing one. Tap Use Photo or Use Video, or tap Add to add an existing one. You can also scan documents and add them to your notes.
