Key features include: User Management: Smooth B2B and B2C registration and login; Benefits: Fuel card management, loyalty rewards, and discount tracking; Maps & Geolocation: Searching for stations and points of interest; E-Mobility: Starting/stopping EV charging sessions directly from the app with real-time (live) status tracking; Advanced Features: CarPlay integration (MVP) and dynamic widgets for quick access to key information.
