Mobile applications differ from traditional software applications in several key aspects, including platform, interface, and user interaction. Mobile apps are typically designed for specific mobile devices and operating systems, such as iOS and Android, requiring responsive design to accommodate varying screen sizes. They emphasize touch-based interactions and often integrate with device features like GPS and cameras. In contrast, traditional software often targets desktop or laptop environments, focusing on keyboard and mouse interactions. The distribution models also differ, as mobile apps are generally distributed through app stores, while traditional software can be installed from various sources.
