A mobile app, or simply an app, is a software application designed to run on smartphones, tablets, and other mobile devices. Mobile apps can be native (developed for a specific platform, such as iOS or Android) or cross-platform (designed to run on multiple platforms). Some popular types of mobile apps include games, social media apps, productivity apps, and utility apps. They can be downloaded from app stores such as the Apple App Store or Google Play Store.
Mobile app development refers to the process of creating software applications that run on a mobile device, such as a smartphone or tablet. There are two major mobile operating systems: Android and iOS.
Android app development is done using Java programming language and the Android software development kit (SDK). The Android SDK provides developers with the tools and APIs needed to build, test, and debug their applications for the Android platform.
iOS app development is done using Swift or Objective-C programming languages and the iOS software development kit (SDK). The iOS SDK provides developers with the tools and APIs needed to build, test, and debug their applications for the iOS platform.
