Where to find and download apps
Apps live in official stores that match your device. On an iPhone or iPad, that's the App Store. On Android phones, it's Google Play. On Windows computers, it's the Microsoft Store. On Mac computers, it's the App Store. Each store is built into your device — you don't need to hunt for it.
The store icon usually looks like a shopping bag or grid of dots. Open it the same way you'd open any other app: tap or click the icon on your home screen or in your applications folder. Once inside, you search for the app by name, browse categories, or look at what's trending. When you find the app you want, the download button is usually labeled "Get" or "Install" rather than "Download".
Never download apps from random websites or links in emails, even if they claim to be the real app. Fake versions can steal your passwords or infect your device. Stick to the official store for your device type.
Key Takeaways
- iPhone and iPad users find apps in the App Store; Android users find them in Google Play; Windows users find them in the Microsoft Store; Mac users find them in the App Store.
- Open your device's store app, search for the app by name, and tap or click the "Get" or "Install" button to start the download.
- The download and installation happen automatically once you start — you don't need to do anything else unless the app asks for permission to access your camera, location, or contacts.
- Only download from the official store for your device; downloading from websites or email links risks installing fake or harmful versions.
The download and installation process
After you tap or click "Get" or "Install", the app begins downloading to your device. On most phones and tablets, this takes seconds to a few minutes depending on the app's size and your internet speed. You'll see a progress circle or bar while it downloads. Once the download finishes, the app installs automatically — you don't need to do anything.
The button will change from "Get" to "Open" once the app is ready to use. Tap or click "Open" to launch the app for the first time. On a computer, the app usually appears in your applications folder or on your desktop after installation finishes.
Some apps ask for permission to access your camera, location, contacts, or photos the first time you open them. You'll see a popup asking "Allow" or "Don't Allow". You can usually change these permissions later in your device's settings if you change your mind.
What happens if the download stalls or fails
If a download stops partway through, check your internet connection. Switch to WiFi if you're on mobile data, or restart your WiFi router if it's slow. Then go back to the store, find the app again, and tap or click "Get" or "Install" once more. The store will usually resume the download rather than starting over.
If an app won't download at all, the most common reasons are: your device doesn't have enough storage space left, the app isn't available in your country or region, or your device is too old to run that app. Check how much storage you have left in your device's settings. If you're low on space, delete photos, videos, or apps you don't use anymore, then try again.
If the app still won't download after you've freed up space, restart your device. Power it off completely, wait 10 seconds, then turn it back on. This clears temporary files that sometimes block downloads. Then open the store and try downloading the app again.
Updating apps after you download them
Apps release updates regularly to fix bugs, add features, or improve security. Your device can update apps automatically, or you can update them yourself. On iPhone, go to the App Store, tap the profile icon in the top right, scroll down to "Available Updates", and tap "Update" next to any app. On Android, open Google Play, tap your profile icon, select "Manage apps & device", go to the "Updates" tab, and tap "Update" next to the app you want.
You can also turn on automatic updates so apps update themselves in the background without you doing anything. On iPhone, go to Settings > App Store and turn on "App Updates". On Android, open Google Play, tap your profile icon, select "Settings", go to "Network preferences", and turn on "Auto-update apps".
Updates usually take a few minutes and happen in the background. You don't need to do anything while they're installing. If an update is large, your device might wait until you're on WiFi to download it automatically.
Removing apps you no longer want
If you download an app and decide you don't want it, you can remove it from your device. On iPhone, press and hold the app icon on your home screen, tap "Remove", then tap "Remove from Home Screen" or "Remove App" depending on what you want. On Android, press and hold the app icon, tap "Uninstall", then confirm. On Windows, right-click the app in the Start menu and select "Uninstall". On Mac, drag the app from your Applications folder to the Trash.
Removing an app frees up storage space on your device. If you change your mind later, you can download it again from the store — your device will remember that you had it before, and the download will be faster the second time.
Downloading apps on older devices or slow internet
If your device is several years old, some newer apps won't download because they require a newer version of your operating system. Check your device's settings to see what version you're running, then look at the app's requirements in the store before you try to download it. The store usually shows a message like "This app requires iOS 15 or later" if your device is too old.
If your internet is slow, download apps over WiFi instead of mobile data. Mobile data is often slower and may have data limits that make large downloads expensive. WiFi is faster and unlimited. If you're on the go and only have mobile data, wait until you can reach WiFi before downloading large apps.
Some apps let you download them in stages — you can start using the app while the rest downloads in the background. The store will tell you if an app supports this. Look for language like "Install as you go" or "On-demand delivery".
Frequently Asked Questions
Do I have to pay for every app I download?
No. Many apps are free, and you can download them without paying anything. Some apps cost money upfront — you'll see the price in the store before you download. Other apps are free to download but charge money for extra features inside the app. The store always shows you the price before you start the download.
Can I download the same app on multiple devices?
Yes, if you use the same account on both devices. On iPhone and iPad, use the same Apple ID on both devices. On Android phones and tablets, use the same Google account. On Windows and Mac, use the same Microsoft account. Once you're signed in with the same account, you can download the app on each device. Some apps let you use them on multiple devices at once; others limit you to one device at a time.
What if I see a warning that an app is from an unknown developer?
This warning appears on Mac computers when you download an app that isn't from the App Store. It doesn't mean the app is dangerous — many legitimate apps are distributed outside the store. If you trust the source, you can allow it to run. Go to System Preferences > Security & Privacy, find the app in the list, and click "Open Anyway". On iPhone and Android, apps can only come from the official store, so you won't see this warning.
Why does an app ask for permission to access my location or camera?
Apps ask for permission because they need access to that part of your device to work. A maps app needs your location to show where you are. A video chat app needs your camera and microphone. You can say no to any permission, but the app might not work fully. You can change permissions later in your device's settings without uninstalling the app.
Can I download an app if I don't have much storage space left?
It depends on the app's size. Small apps might download even if you have only a few hundred megabytes free. Large apps need more space. Check how much storage you have left in your device's settings, then look at the app's size in the store. If you're low on space, delete photos, videos, or apps you don't use, then try downloading again.
