Mobile applications (apps) are software designed for smartphones, tablets, and other mobile devices, featuring user-friendly interfaces for easy navigation. They serve various functions, including electronic vehicle charging (EVC), point of sale (POS), payment processing, and e-commerce. Developed mainly for iOS and Android, many apps require internet access for synchronization and updates. They also incorporate security features to protect user data. Available for download from app stores, mobile apps can be native (platform-specific), web-based (browser-accessed), or hybrid (combining elements of both).
