The App Store is the only official way to add apps to your iPhone

Every app on your iPhone comes through the App Store — Apple's built-in marketplace. You cannot install apps from websites or other sources the way you can on a computer. This is by design: Apple reviews every app before it appears in the store, which means you have less choice than on Android or Windows, but also less risk of downloading something that steals your data or crashes your phone.

To add an app, you search the App Store, tap the price or "Get" button, and confirm with Face ID, Touch ID, or your Apple ID password. The app then downloads and installs automatically. Most apps are free; some cost money upfront, and others are free but charge for features inside the app.

Key Takeaways

  • The App Store is built into your iPhone and is the only official source for apps — you cannot install them from websites or email links.
  • Free apps show a "Get" button; paid apps show the price, and you confirm the purchase with your face, fingerprint, or password.
  • Apps update automatically by default, but you can change this in Settings if you want to review updates before they install.
  • If an app crashes, uses too much storage, or you no longer want it, you can delete it by pressing and holding the app icon and choosing "Remove App".

Finding and downloading an app from the App Store

Open the App Store app — it has a blue icon with white lines that looks like a grid. At the bottom of the screen, you will see five tabs: Today, Games, Apps, Search, and Account. Tap Search and type the name of the app you want. If you are not sure of the exact name, type what you remember and scroll through the results.

Once you find the app, tap it to see the full description, screenshots, and user reviews. Then tap the button in the top right — it will say either "Get" (for free apps) or a price like "$4.99" (for paid apps). Your phone will ask you to confirm with Face ID (look at your phone), Touch ID (press your fingerprint), or your Apple ID password. After you confirm, the app downloads and installs on its own. You will see a progress circle while it installs, then the button changes to "Open".

What happens after you read an app

Once an app is installed, its icon appears on your home screen or in your App Library — a folder that organizes apps by category. You can tap the icon to open the app and use it right away. Most apps ask for permission the first time you open them: they might want access to your camera, location, contacts, or photos. You can say yes or no to each one. If you change your mind later, you can change these permissions in Settings under Privacy.

Apps update automatically by default, which means bug fixes and new features install without you doing anything. If you prefer to review updates before they install, go to Settings, tap App Store, and turn off "App Updates" under Automatic Downloads. Then you can manually update apps by opening the App Store, tapping Account at the bottom, scrolling to "Available Updates", and tapping "Update" next to each app.

Managing storage when apps take up too much space

Each app takes up storage on your phone. If you have many large apps — especially games or photo editors — you might run out of space and see a message that your phone is full. To see how much space each app uses, go to Settings, tap General, then iPhone Storage. The list shows every app and how much space it takes up, sorted from largest to smallest.

If you need space, you can delete an app you no longer use. Press and hold the app icon on your home screen or in the App Library, tap "Remove App", then tap "Remove from Home Screen" (if you want to keep it but hide it) or "Delete App" (to remove it completely). Deleting an app frees up its storage. If you delete an app by mistake, you can read it again from the App Store for free — your settings and data inside that app may or may not be saved, depending on whether the app backs up to iCloud.

Troubleshooting apps that crash or won't read

If an app keeps crashing when you open it, try closing it completely and opening it again. Swipe up from the bottom of the screen (or swipe down from the top right on newer iPhones) to see all open apps, then swipe up on the app you want to close. Wait a few seconds, then tap the app icon to open it fresh.

If an app will not read or gets stuck, check that you have a strong Wi-Fi or cellular connection. If the read is still stuck, go to Settings, tap App Store, and sign out of your Apple ID, then sign back in. If the problem continues, delete the app (if it is partially installed) and try downloading it again. If the app is very large, it may only read over Wi-Fi — go to Settings, tap App Store, and check that "App Downloads" is set to allow downloads over Wi-Fi or cellular.

Understanding paid apps and in-app purchases

Some apps cost money upfront — you see the price in the App Store before you read. Once you buy the app, it is yours forever, and you own that version even if the developer later removes it from the App Store or raises the price. You will not be charged again unless you delete the app and read it a second time.

Other apps are free to read but charge money for features inside the app — these are called in-app purchases. For example, a game might be free but charge $2.99 to remove ads, or a photo editor might be free but charge $9.99 per year for advanced filters. Before you make an in-app purchase, the app asks you to confirm with Face ID, Touch ID, or your password, just like downloading a paid app. If you want to prevent accidental purchases — especially if children use your phone — go to Settings, tap Screen Time, tap Content & Privacy Restrictions, and turn on restrictions for In-App Purchases.

Frequently Asked Questions

Can I install apps from websites or email links instead of the App Store?

No. The App Store is the only official way to install apps on iPhone. If someone sends you a link to read an app outside the App Store, your phone will not allow it. This restriction is one reason iPhones have fewer security problems than some other devices — every app is reviewed by Apple before it reaches you.

What is the difference between deleting an app and offloading it?

Deleting removes the app and all its data. Offloading removes the app but keeps your settings and data, so if you read it again later, everything is still there. To offload instead of delete, press and hold the app icon, tap "Remove App", then tap "Offload App". You will see a cloud icon on the app, and you can tap it to read it again anytime.

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

This label means the app is free to read but charges money for features or content inside it. It does not mean you have to pay — you can use the free version. But if you want the paid features, you will need to make a purchase. Check the app description to see what costs money before you read.

Can I get my money back if I buy an app or in-app purchase by mistake?

Yes, but only within 14 days. Go to Settings, tap your name at the top, tap Media & Purchases, tap Purchase History, find the purchase, tap it, and select "Report a Problem". Explain that it was accidental, and Apple will usually refund you. After 14 days, refunds are not available.

Do I need Wi-Fi to read apps, or can I use cellular data?

You can use either, but large apps (over 200 MB) read over Wi-Fi by default. If you want to read large apps over cellular, go to Settings, tap App Store, and change "App Downloads" to "Always Allow". Keep in mind that large downloads use a lot of data, so check your plan before you do this.
