WappyWap is a free mobile application and web-based platform that allows registered users to contact the owner of any vehicle through its license plate. The community of users, called "Wappers," can send and receive "Wappies" to communicate with each other. The app provides a quick and easy way to communicate with other drivers without the need for personal details like phone numbers or email addresses.

Aside from enhancing privacy and security, WappyWap also provides several useful features. Drivers can use the app to contact other drivers in situations such as technical problems, stolen or vandalized vehicles, or blocked traffic. Additionally, WappyWap can notify drivers of traffic, closed roads, diversions, accidents, and speed cameras. The app also provides a way to meet other drivers or connect with buyers and sellers of specific car models. Users can compose their own messages or use ready-made Wappies for different situations and can add photos or videos to their messages.
