Shake to Undo: The Fastest Way to Fix Mistakes on iPhone and iPad

Three Ways to Undo on iPhone and iPad

Apple actually provides three different methods to undo your last action. Each one works system-wide, and you can use whichever feels most natural to you:

What Can You Actually Undo?

Shake to Undo is more versatile than most people realize. It doesn’t just work with text — it covers a surprisingly wide range of actions across the operating system:

• Typing: Undo accidental deletions, pastes, autocorrections, and formatting changes in any text field.
• Email: Accidentally archived or trashed an email in Mail? Shake immediately to bring it back to your inbox.
• Photos: Undo edits in the Photos editor. If you crop, filter, or adjust an image and don’t like it, shake to step back.
• Drawing: In Notes, Freeform, or Markup, shake to undo the last stroke or eraser action.
• Drag and Drop: If you accidentally move a file, photo, or widget to the wrong spot, shake to reverse the move.
• Third-party apps: Most apps that use standard iOS text fields and editing frameworks support system undo automatically.

How to Undo Multiple Steps

One undo isn’t always enough. If you need to go back several actions, you have two options:

Keep shaking. Each shake triggers another undo step. So if you deleted three sentences one by one, three shakes brings all three back. The dialog appears each time, which makes it slightly slow for multi-step undo.

Use the three-finger swipe instead. This is faster for multiple undos because it doesn’t show a dialog — each left swipe undoes one action immediately. On iPad especially, you can swipe left rapidly three or four times to fly through your undo history.

How to Disable Shake to Undo

Some people find Shake to Undo annoying because it triggers accidentally — during workouts, on public transport, or just from normal movement. Fortunately, you can turn it off without losing the ability to undo:

Go to Settings → Accessibility → Touch and toggle off Shake to Undo. The three-finger swipe and double-tap gestures still work as alternatives, so you don’t lose undo functionality entirely.

The Floating Edit Toolbar

When you double-tap with three fingers, a small floating toolbar appears at the top of the screen with three buttons: Undo, Redo, and Paste. This toolbar is incredibly useful when you’re doing heavy editing, because it lets you tap undo or redo repeatedly without any gestures at all. The toolbar disappears after a few seconds of inactivity, or you can swipe it away.

Undo on iPad with Keyboard

If you use a hardware keyboard (Magic Keyboard, Smart Keyboard Folio, or any Bluetooth keyboard), the familiar Cmd+Z shortcut works for undo and Cmd+Shift+Z for redo. This is identical to how undo works on Mac and gives you the fastest, most reliable undo experience on iPad.

Tips for Shake to Undo

Act quickly. Shake to Undo works best immediately after the mistake. If you continue typing or performing other actions, the undo history may roll forward and you’ll undo the wrong thing.

Don’t shake too hard. A gentle, quick wrist flick is all you need. You’re not trying to mix a cocktail — just a short back-and-forth movement that the accelerometer can detect.

Remember: Redo exists. If you undo something and realize you actually wanted to keep it, shake again (or three-finger swipe right) to redo. Many people forget that redo is just as accessible as undo.
