The ゼッテリア app is designed to enhance the experience of using ゼッテリア by offering convenient features for its users. This free iPhone application allows customers to place mobile orders for takeout without needing to visit the store physically. Users can register their credit cards for easy payment, provided they have a 3D secure authentication enabled card. Orders can be scheduled for pickup at designated times, helping to avoid waiting in line, with options to order 24/7 and even up to a month in advance at select locations.

In addition to mobile ordering, the app offers a rewards system where users can earn common points through their purchases. The app also provides access to exclusive coupons, enhancing the value of each order. A store locator feature allows users to find nearby locations or search by address, making it easier to enjoy ゼッテリア’s offerings.
