ADSUN by Adsun JSC is a free travel and navigation app designed to monitor vehicles conveniently through smartphones or tablets with an internet connection. The app requires users to log in using their existing accounts on Ánh Dương's journey monitoring system.

ADSUN is perfect for those who want to keep track of their vehicles without the hassle of using a separate device. With just a few taps on your phone or tablet, you can easily monitor your vehicle's location and movements. However, it's important to note that ADSUN is still in the testing phase, and the developers are eager to receive feedback and suggestions from users to improve the product.
