TXT Official Light Stick is the go-to mobile app for fans of the K-Pop group TXT. This app serves as the official mobile app for the TXT OFFICIAL LIGHT STICK, a Bluetooth-enabled light stick that fans use to show their support during concerts and events.

One of the key features of the app is its Bluetooth connection capability. Fans can easily connect their light sticks to their smartphones via Bluetooth, allowing them to enjoy various stage effects during concerts. Additionally, the app offers a self-mode feature that lets fans change the LED lighting color to their preferred color.

Before the concert, fans need to check their ticket information and register their seat information on the app. It is important to enjoy the show from the same seat that is registered on the light stick to avoid any issues with the wireless control feature. Fans are also advised to check the battery level of their light stick before the show to avoid it shutting off during the concert.

Overall, the TXT Official Light Stick app is a must-have for any fan of the K-Pop group TXT who wants to fully enjoy their concerts and events. The app is free to download and use, but it requires certain access permissions such as device storage, phone status and identity, camera, GPS, and BLE to function properly.
