How to Install an App From Your iPhone

Getting an app onto your iPhone from the App Store

The App Store is the official place to find and install apps on your iPhone. You open it, search for what you want, and tap a button to read it — the app then installs automatically and appears on your home screen. Most apps are free, though some cost money and will ask you to confirm the purchase before downloading.

You need an Apple ID to read anything, even free apps. If you set up your iPhone when you first got it, you already have one. If you're not sure, go to Settings, tap your name at the top, and if you see an Apple ID listed there, you're set. If not, you can create one for free in Settings by tapping "Create New Apple ID" and following the prompts.

Key Takeaways

Open the App Store app (the blue icon with a white square), search for the app by name, and tap the cloud icon or price button to read it.
Free apps read and install automatically; paid apps ask you to confirm the purchase using Face ID, Touch ID, or your Apple ID password.
Downloaded apps appear on your home screen and in the App Store under "Purchased" if you ever need to reinstall them.
If an app won't read, check that you have Wi-Fi or cellular data, enough storage space, and that your Apple ID password is correct.
Apps update automatically by default, but you can turn off automatic updates in App Store settings if you prefer to update them manually.

Opening the App Store and finding an app

The App Store app comes built into every iPhone — it's the blue icon with a white square on it. Tap it to open. At the bottom of the screen you'll see five tabs: Today, Games, Apps, Arcade, and Search. The easiest way to find a specific app is to tap the Search tab (the magnifying glass icon on the far right).

Type the name of the app you want into the search box at the top. As you type, the App Store shows suggestions. Tap the one you want. You'll see the app's page with screenshots, a description, reviews, and a button at the top right. That button will either say a price (like $4.99), say "Get," or show a cloud icon with a down arrow if you've downloaded it before.

Downloading and installing a free app

If the app is free, the button says "Get." Tap it once. The button will change to show a loading circle while the app downloads. After a few seconds, it will change again to say "Install." Tap it. Your iPhone will ask you to confirm using Face ID (look at the phone), Touch ID (press your finger on the home button or side button), or your Apple ID password. Do whichever one your phone is set up for.

Once you confirm, the app installs automatically. The button will change to "Open." You can tap it to start the app right away, or just wait — the app is now on your home screen and you can find it there anytime. The whole process usually takes less than a minute on Wi-Fi.

Downloading and installing a paid app

Paid apps work the same way, except the button shows the price instead of "Get." Tap the price button. It will change to say "Buy App." Tap it again. Your iPhone will ask you to confirm the purchase using Face ID, Touch ID, or your Apple ID password — the same way it does for free apps. Once you confirm, the app downloads and installs.

The purchase is charged to the payment method linked to your Apple ID — usually a credit card or debit card you set up when you created the ID. If you don't have a payment method on file and try to buy an app, your iPhone will ask you to add one before the purchase goes through.

What to do if an app won't read

If you tap "Get" or "Buy" and nothing happens, or the read gets stuck, check these things first. Make sure you have Wi-Fi or cellular data turned on — if you're on Wi-Fi, make sure you're actually connected to the network. Go to Settings and tap Wi-Fi to check. If you're using cellular data, make sure it's turned on in Settings under Cellular.

Next, check how much storage space your iPhone has left. Go to Settings, tap General, then tap iPhone Storage. If you're using more than 90 percent of your storage, the read might fail. Delete apps or photos you don't need to free up space. If the read still won't start, sign out of your Apple ID and sign back in. Go to Settings, tap your name at the top, scroll down, and tap "Sign Out." Then sign back in with your Apple ID and password and try downloading again.

Finding apps you've already downloaded

Once you read an app, it stays in your App Store account forever, even if you delete it from your iPhone. If you want to read it again later, you don't have to pay for it a second time. Open the App Store, tap the profile icon in the top right corner (it looks like a circle with your photo or initials), and tap "Purchased." You'll see a list of every app you've ever downloaded. Find the one you want and tap the cloud icon to read it again.

You can also find recently downloaded apps on your home screen. When you read an app, it appears in the top-left area of your home screen, or in the folder where you keep similar apps if you've organized them. Swipe left through your home screen pages to find it, or use Spotlight search — swipe down from the top of the screen and type the app's name.

Turning automatic updates on or off

By default, your iPhone automatically updates all your apps in the background when you're connected to Wi-Fi. This means you always have the newest version with bug fixes and new features. If you prefer to update apps manually and choose when that happens, you can turn this off.

Open the App Store, tap the profile icon in the top right, and tap "Settings." Look for "App Updates" and toggle it off. Now when an update is available, you'll see a red number on the App Store icon showing how many apps have updates waiting. Open the App Store, go to your profile, tap "Purchased," and you'll see which apps have updates. Tap "Update" next to any app you want to update, or tap "Update All" to update everything at once.

Frequently Asked Questions

Can I read an app without Wi-Fi?

Yes, if you have cellular data turned on. Large apps might read slowly on cellular, and some people turn off cellular downloads in Settings to avoid using their data plan. Go to Settings, tap App Store, and toggle "App Downloads" to choose Wi-Fi only or Wi-Fi and Cellular.

What if I see "This app is not available in your country"?

Some apps are only sold in certain countries because of licensing or legal rules. You cannot read them on an iPhone set to a different country. If you have an Apple ID from another country, you can create a second Apple ID set to that country and read the app there, but this is complicated and not recommended for most people.

Do I need to pay for an app every time I read it?

No. Once you buy an app, it's tied to your Apple ID forever. You can delete it and read it again for free anytime. This works across all your Apple devices too — if you buy an app on your iPhone, you can read it free on your iPad or Mac using the same Apple ID.

Why does an app say "Offers In-App Purchases"?

The app itself is free or paid, but it also lets you buy extra features, coins, or content inside the app after you read it. You don't have to buy anything — the app works without them. If you want to prevent accidental purchases, go to Settings, tap Screen Time, tap Content & Privacy Restrictions, and turn on restrictions for In-App Purchases.

Can I read apps from somewhere other than the App Store?

On a regular iPhone, no — the App Store is the only official place to get apps. Some websites claim to let you read apps from elsewhere, but Apple doesn't allow it and these are usually not safe. Stick with the App Store.
