The user does not need to manually check for new 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 is already familiar with the general way the software looks, feels, and operates. Because software must conform to device guidelines, separate apps have a greater consistency of interface and user experience. Instead of needing to trust a wide array of software vendors, trust can be placed in a single entity (the store operator). Users can search for new software in one familiar place on their device. The software is then digitally signed by the store operator, to prevent it from being altered without the operator's knowledge and approval. The code of each app is reviewed to make sure it contains no malware or viruses, and conforms to other guidelines for the user's device. For instance, Apple inspects all software on the macOS and iOS App Stores, and Google inspects all software on the Play Store. The software available on an app store is officially approved by the store operator.
