iSmarport is a free Android application developed by Shenzhen Intelligent Age Technology Co. Ltd. that works in conjunction with the HJ08 watch. This app connects to the HJ08 watch and provides various features to the users. It allows users to read SMS and notifications and reply to them quickly. The app also enables users to make and receive calls directly from the watch, without the need to open the mobile phone. Additionally, the app provides a statistical table of the user's heart rate, blood pressure, oxygen, sleep, and exercise data measured by the HJ08 watch. Finally, the app locates the user's geographical location through the location information function when the user starts running mode and draws the user's movement track after the end of running, to help the user better understand their health data generated during running.

The iSmarport app is a must-have for HJ08 watch users who want to keep track of their health and fitness. With its comprehensive features, the app provides users with an easy and efficient way to monitor their health data and stay connected without the need to open their mobile phone.
