메타킹 introduces its official application where users can order and pay before visiting the store, along with experiencing various membership benefits. The app offers features such as smart ordering to place orders and make payments before visiting the nearby store without waiting. Users can also earn stamps, store-specific champion badges, and enjoy benefits based on their membership level.

The stamp accumulation method awards one stamp per beverage ordered via smart ordering (for beverages priced above 1,500 won) and upon collecting 10 stamps, users receive a coupon for a 1,500 won HOT Americano. These coupons can be used at any nationwide 메타킹 store, with exceptions listed on the store's website. Upgrade your badge level by ordering over 10,000 won via smart ordering, earning up to three levels of badges with the ultimate champion badge available at the third level. Membership levels range from Light, Trophy (achieved with 5 stamps), to Kingkong (achieved with 50 stamps), each offering distinct benefits accessible through the app's My Page section.
