TREASURE LIGHT STICK is a lifestyle app developed by YG PLUS Inc. for iPhone users. This app allows users to connect their light stick to their smartphone via Bluetooth. By turning on the light stick and pressing the button twice, users can enter Bluetooth mode. When the Bluetooth function of the smartphone is turned on and the light stick is close to the smartphone screen, the two devices become interlocked.

The app requires certain access rights, as per the Paragraph 1 of Article 22-2 of the Information and Communications Network Act. These access rights include storage access for performance information, location access for BLE (Bluetooth Low Energy) connections, and BLE access for connecting cheering tools.

With its simple and intuitive interface, TREASURE LIGHT STICK provides a convenient way for users to connect and control their light stick with their smartphone. Whether you're at a concert, a fan event, or simply want to show your support for your favorite artist, this app enhances the overall experience by allowing you to easily customize and control your light stick.
