In general, an app store is an application that enables a user to find software, and install it on their computer or mobile device. It's a collection of free and commercial software, approved for use on your device. You can browse, purchase, download, install, and update software through your device's app store.
Benefits of using an app store
The software available on an app store is officially approved by the store operator. For instance, Apple inspects all software on the macOS and iOS App Stores, and Google inspects all software on the Play Store. The code of each app is reviewed to make sure it contains no malware or viruses, and that it conforms to other guidelines for the user's device. The software is then digitally signed by the store operator, to prevent it from being altered without the operator's knowledge and approval.
Other benefits of app stores include:
- Convenience. Users can search for new software in one familiar place on their device.
- Trust. Instead of needing to trust a wide array of software vendors, trust can be placed in a single entity (the store operator).
- Consistent experience. Because software must conform to device guidelines, separate apps will have greater consistency of interface and user experience. The user is already familiar with the general way the software looks, feels, and operates.
- Easier updates. When an update is available for software installed from the app store, the store can notify the user that an update is available. The user does not need to manually check for new updates. If multiple updates are available, they can be installed by the app store all at once.
macOS App Store (Apple computer)
The macOS App Store was launched on January 6, 2011. It is part of the macOS operating system, and may be used to find, download, and install software for a Mac. The App Store is also used to install security updates, and upgrade to newer versions of macOS.
On macOS computers, the App Store is located in the Applications folder, and as a default icon on the dock.
The macOS App Store is closely integrated with a macOS feature called Gatekeeper, which verifies the digital signature of all apps downloaded from the Internet. For information about changing Gatekeeper settings, see Changing Gatekeeper settings in macOS.
iOS App Store (Apple iPad and iPhone)
The iOS App Store provides software downloads for the iPad and iPhone. It was launched on July 10, 2008. Unlike in macOS, the iOS App Store is not used for updating the iOS system, and cannot be configured to lower security settings. The only way to install software on an iOS device without using the App Store is to jailbreak the device, which voids its warranty.
On iOS devices, the App Store is located on the home screen. It is a core part of iOS, and cannot be removed.
Google Play Store (Android tablet and smartphone)
The Google Play Store is an app store provided by Google for Android devices, the Chrome web browser, and Chrome OS computers. It was launched on October 22, 2008, as "Android Market." It was later integrated with two other Google services, Google Music and Google eBookstore, to create Google Play.
Unlike other App Stores, Google Play allows users to purchase digital music and e-books.
On most Android devices, the Play Store is available on the home screen.
On the web, the Play Store can be accessed at play.google.com/store.
Microsoft Store (Microsoft PC)
Tip: The Microsoft Store does not offer updates to the Windows operating system. To update Windows, use Windows Update instead.
