Moving Apps to Your SD Card to Free Up Phone Storage

How to move an app to your SD card

You can move most apps from your phone's internal storage to an SD card through your phone's Settings menu. The exact steps depend on whether you have an Android phone (which supports this) or an iPhone (which does not). On Android, you open Settings, find the app you want to move, and select the option to change its storage location. The process takes about 30 seconds per app and frees up space on your phone immediately.

Not every app can be moved. System apps that came with your phone usually stay in internal storage. Some newer apps are designed to run only from your phone's main storage, and their developer has locked them there. You will see which apps can be moved because they will have a "Move to SD card" button available — if the button is grayed out or missing, that app cannot be moved.

Key Takeaways

Android phones let you move apps to an SD card through Settings > Apps, but iPhones do not support this feature at all.
Only apps you downloaded can usually be moved; system apps and some newer apps are locked to internal storage.
Moving an app takes about 30 seconds and frees up space on your phone right away, though the app will run slightly slower from the SD card.
If an app crashes after you move it, moving it back to internal storage usually fixes the problem.

Step-by-step: Moving an app on Android

Open your phone's Settings app. Scroll down and tap Apps or Application Manager — the exact name varies by phone brand. You will see a list of every app on your phone.

Find the app you want to move and tap its name. A details screen will open showing how much space the app uses. Look for a button that says Storage or Change. Tap it. A menu will appear with two options: Internal Storage and SD Card. Tap SD Card. Your phone will move the app, which usually takes 10 to 30 seconds. When it finishes, the button will now show "Move to Internal Storage," confirming the app is on your SD card.

Repeat this process for each app you want to move. You can move as many apps as your SD card has space for, though moving too many apps to the card can slow down your phone slightly because SD cards are slower than internal storage.

Why your app might not have a move option

If you tap an app and do not see a "Move to SD Card" button, or the button is grayed out, the app cannot be moved. This happens for three reasons: the app is a system app that came with your phone, the app's developer has locked it to internal storage only, or your SD card is not formatted correctly for app storage.

System apps like Phone, Messages, Settings, and Google Play Store cannot be moved because your phone needs them to run. If you try to remove them, your phone will not work properly. Some newer apps from major developers like Netflix or Spotify are intentionally locked to internal storage because they run faster there or because the developer chose not to support SD card storage.

If you have an SD card inserted but still do not see the move option, your card may not be formatted as adoptable storage. This is a technical setting that tells your phone the card can hold apps. You can reformat your SD card in Settings > Storage, though this will erase everything on it first.

What happens to an app when you move it

Moving an app to your SD card does not change how it works or what it can do. You launch it the same way, it has the same features, and your data inside the app stays the same. The only difference you might notice is that the app takes slightly longer to open because the SD card is slower than your phone's internal storage.

If an app crashes or behaves strangely after you move it to the SD card, move it back to internal storage. Some apps have bugs that only show up when they run from an SD card, and moving them back usually fixes the problem. You can also remove the SD card without damaging the app — your phone will just move it back to internal storage automatically.

How much space you can free up

The amount of space you free up depends on which apps you move. Large apps like games, video editors, or streaming services can use 100 megabytes to several gigabytes each. Moving three or four large apps can free up 1 to 2 gigabytes of space, which is often enough to get your phone running smoothly again.

Check how much space each app uses before you move it. In the app's details screen in Settings, you will see a number that says "Storage used" or "Size." Apps under 50 megabytes will not free up much space, so focus on the larger ones first. If you move all the apps you can and still need more space, you may need a larger SD card or to delete apps you no longer use.

Moving apps on iPhone does not work this way

iPhones do not support moving apps to an SD card because iPhones do not have SD card slots. Apple designed iPhones to store everything on internal storage, and there is no way to change this. If your iPhone is running out of space, your options are to delete apps you do not use, offload apps (which removes the app but keeps your data), or upgrade to a phone with more storage.

To offload an app on iPhone, open Settings, tap General, then iPhone Storage. Find the app and tap Offload App. This removes the app but saves your data, so you can reinstall it later without losing your progress. This frees up some space, though not as much as moving an app to an SD card would on Android.

Frequently Asked Questions

Will moving an app to my SD card make it slower?

Yes, slightly. SD cards are slower than your phone's internal storage, so apps on the card take a bit longer to open and may run a little slower. For most apps this is not noticeable, but games and video editors might feel sluggish. If an app feels too slow on the SD card, move it back to internal storage.

Can I move apps if my SD card is not formatted?

No. Your SD card must be formatted as adoptable storage before your phone will let you move apps to it. You can format it in Settings > Storage, but this erases everything on the card first. After formatting, you can move apps to it.

What happens to my apps if I remove the SD card?

Your phone will automatically move the apps back to internal storage when you remove the card. You will not lose any data or settings. When you put the card back in, your phone will move them back to the card if there is space.

Can I move system apps like Gmail or Google Maps?

No, system apps that came with your phone cannot be moved. You can only move apps you downloaded yourself. If you want to free up space, you can uninstall updates to system apps by going to Settings > Apps, tapping the app, and selecting "Uninstall updates."

How do I know if my phone has an SD card slot?

Look for a small slot on the side of your phone, usually near the power button or volume buttons. If you see a thin rectangular opening, your phone has an SD card slot. iPhones never have SD card slots. If you are not sure, search your phone model online — the specs will say whether it supports SD cards.
