The GOT7 Ver3 Official Light Stick app, developed by FANLIGHT, is a lifestyle application designed for fans of the K-pop group GOT7. This app allows users to connect their official light stick to their smartphones and enjoy various light stick performances during concerts.

One of the main features of the app is the Concert Mode, which allows users to pair their light stick with their concert seat information. This enables them to experience synchronized light stick performances during the concert. It's important to note that this feature is only available during the concert period.

Additionally, the app provides a Battery Level Check function, allowing users to easily check the battery level of their light stick. This ensures that the light stick has sufficient battery power during the concert. However, it's important to note that the functionality of this feature may vary depending on battery performance and smartphone model.

Overall, the GOT7 Ver3 Official Light Stick app offers a convenient and immersive experience for fans of the K-pop group. With its various features, fans can enhance their concert experience and show their support for GOT7 using their official light stick.
