This article explains various options for undoing a typo, mistake, or deleted note in the Notes app on an iPhone or iPad.

When you delete a note, you can undo it. Apple provides two ways to recover a deleted note.

If you just deleted the note, a Shake to Undo will bring up the Undo Trash Note option. Tap Undo to restore your note.

Otherwise, navigate to the main Folders menu in Notes. Tap Recently Deleted to access deleted notes. Apple places deleted notes in the Recently Deleted folder for 30 days, after which the system permanently deletes your notes.
