You've been typing for twenty minutes. It’s that perfect grocery list, a brainstorm for your new side hustle, or maybe just a venting session about your neighbor’s barking dog. Then, it happens. Your thumb slips. A giant chunk of text vanishes into the white void of the screen. Your heart sinks. Panic sets in because, honestly, the iPhone interface is so clean it sometimes feels like there aren't any buttons left to help you.
Don't freak out.
If you're wondering how do you undo in notes on iPhone, you aren't stuck with a blank page. Apple has actually baked about four different ways to fix mistakes into iOS, though some of them feel like secret handshakes. Most people know about the "shake" thing, but that’s honestly the most annoying way to do it. Imagine shaking your $1,000 glass rectangle in a crowded coffee shop just because you deleted a sentence about kale. There are better ways.
The Three-Finger Tap: The Pro Move
Forget shaking. The most reliable way to undo a mistake in the Notes app—and almost anywhere else in iOS—is the three-finger gesture. It’s been around since iOS 13, yet I still see people struggling with the "Undo" popup.
Here is how it works. Double-tap the screen with three fingers. Just a quick, light tap. Boom. Your deleted text reappears. If you want to redo something you just undid, you triple-tap with three fingers. It’s fast. It’s subtle. It doesn't make you look like you're trying to mix a martini with your phone.
But there is a variation. You can also swipe.
If you swipe from right to left with three fingers, it functions as a "step back" command. It’s like hitting Ctrl+Z on a mechanical keyboard but much more fluid. Swiping from left to right does the opposite—it redoes the action. This is particularly useful if you accidentally undid too much and realized that the original sentence wasn't actually that bad.
The "Shake to Undo" Legacy
We have to talk about it because it’s the default. "Shake to Undo" is the feature everyone discovers by accident when they’re walking and typing. You trip, the phone wobbles, and suddenly a box pops up asking if you want to undo your typing.
It works, sure. But it’s clumsy. If you find it annoying, you can actually kill this feature in your settings. Head over to Settings, hit Accessibility, then Touch, and toggle off Shake to Undo.
Why would you do that? Because sometimes you’re just moving, and the popup interrupts your flow. If you’re a power user, you probably rely on the gestures anyway. However, for a lot of people, this is the only way they know how do you undo in notes on iPhone, so it stays on by default.
The Hidden Toolbar Icons
Sometimes gestures fail. Maybe your screen is a bit smudged or your fingers are cold, and the three-finger tap just isn’t registering. If you tap the "Markup" icon—the little pen tip inside a circle at the bottom of a note—you’ll see two curved arrows at the top of the screen.
The one pointing left is your undo button.
The one pointing right is your redo button.
This is the "old school" way. It’s visual. It’s tactile. It’s great for when you’re drawing or sketching in Notes and you want to remove a specific line without messing up the whole image. It’s less "hidden" than the gestures, but it requires an extra tap to get into the Markup menu, which can feel slow if you’re in the middle of a fast-paced writing session.
Dealing with the "Trash" Reality
What if you didn't just delete a word? What if you deleted the entire note?
This happens way more than it should. You swipe left on a note in your list, hit the red trash can, and it’s gone. Or so it seems. Apple knows we’re prone to "fat-fingering" our deletions.

When a note disappears, it doesn't actually go into the digital abyss immediately. It goes to the Recently Deleted folder. This folder lives in your main "Folders" view. It’s basically a purgatory for your thoughts.
Notes stay there for 30 days. Some people think they’re gone forever the second they hit delete, but as long as you haven't manually emptied that folder, you can go in, hit "Edit," select your note, and move it back to your main iCloud or "On My iPhone" folder. If it’s been 31 days, though, you’re likely out of luck unless you have a full device backup in iCloud or on a Mac/PC from before the deletion happened.
Why Does This Matter?
Understanding the nuances of the Notes app is part of mastering the tool you carry everywhere. The app has evolved from a simple yellow legal pad clone into a legitimate powerhouse that supports collaboration, scanning, and complex formatting. But all those features are useless if you’re afraid to type for fear of losing your work.
Actually, the Notes app is remarkably resilient. It auto-saves constantly. Unlike Word docs from 2005, you don't really "lose" progress because of a crash. Most "loss" is user error—accidental selects, accidental deletes, or over-aggressive backspacing.
Actionable Steps to Master Undo
If you want to stop worrying about losing your work, do these three things right now:

- Practice the three-finger tap. Open a blank note, type "Test," delete it, and double-tap with three fingers. Get the muscle memory down. It feels weird at first, but it's the most professional way to handle the "how do you undo in notes on iPhone" problem.
- Check your Recently Deleted folder. See what’s in there. You might find a "brilliant" idea you trashed three weeks ago that actually deserves a second look.
- Decide on Shake to Undo. If you hate the popup, go to Accessibility settings and kill it. If you like the safety net, leave it.
The iPhone is designed to be intuitive, but "intuitive" sometimes means "hidden behind a gesture." Once you know the three-finger trick, you’ll never go back to shaking your phone like a bottle of ketchup.
Focus on your writing. The tech has your back.
