How do I use the Shake to Undo feature on my iPhone and iPad? It's enabled by default, but you can always turn it off in your settings!

Have you ever tried to delete a giant paragraph of text you just typed on your iPhone or iPad? Good news: You don't have to hold backspace and watch all the letters and words disappear, one by one. You can simply shake your iPhone. Shake to Undo can save precious time and simply gets rid of what you just wrote, so you can start fresh with a blank slate.

How to use Shake to Undo in iPhone and iPad.

Shake to Undo works with almost all apps that you can type in, but in order to show you exactly how everything works, I will demonstrate it in Notes.

  1. Type anything.
  2. Physically shake your iPhone or iPad.
  3. Tap Undo.

    Type anything, physically shake your iPhone or iPad, and then tap Undo.

This will delete all the text you wrote since the last change you made, meaning that, if you made a spelling mistake and corrected it (either via autocorrect or by deleting and retyping it), it will take you back to that point. You can keep shaking your iPhone or iPad to undo multiple times.
