KYOKUTO K-DaSSアプリ is a tool designed for service staff to perform maintenance on specialty vehicles manufactured by Kyokuto Kogyo. Some products also offer expanded functionality for end-users to utilize in vehicle and operational management.

One of the key features of this app is the ability to connect to nearby specialty vehicles using short-range wireless communication, allowing users to view vehicle data. The app can acquire and transmit vehicle data and location information, which can be viewed on K-DaSS Web. It's important to note that even when the app is running in the background, data transmission continues as long as the vehicle connection is maintained.
