わくわくハイウェイ is a travel and navigation app developed by 中日本高速道路株式会社 for Android devices. It provides users with a variety of information related to NEXCO中日本's service areas (SA) and parking areas (PA), such as events, gourmet options, shopping information, campaigns, traffic updates, congestion and road conditions, and toll fees.

With this app, users can receive personalized notifications based on their current location and the time they are passing through. The app also offers exclusive services that are only available through the application.

To deliver notifications accurately, the app utilizes GPS and Bluetooth by default, which may result in increased battery consumption. However, users have the option to choose a battery-saving setting that does not utilize GPS and Bluetooth.

Please note that the use of mobile phones while driving is prohibited by road traffic laws. Therefore, it is recommended to use the app when stopped or have a passenger operate it.
