The カラオケBanBan app is an official application for the popular karaoke chain, providing users with an array of features designed to enhance their karaoke experience. With approximately 360 locations nationwide, the app underwent a significant renewal in November 2024, making it more user-friendly and beneficial. Users can present the app's membership card to earn points, which unlock discounts and special offers based on their membership rank.

Key features include a digital membership card that displays a QR code for easy access to reduced rates, and a point system where each point equals one yen, redeemable during payment. Points can be shared among multiple users, provided a QR code is scanned at checkout. Additionally, as users accumulate points, they can rise in rank, leading to increased point earnings and access to exclusive coupons for further savings on karaoke sessions.
