The もち吉公式アプリ, developed by 株式会社もち吉, is the official app for Mochikichi. This app aims to provide users with the latest information about Mochikichi, including event flyers and exclusive coupons.

One of the key features of the app is the store locator, which utilizes GPS to help users find nearby stores. Users can also search for stores based on keywords or addresses. Additionally, users can view the latest flyers from their favorite stores by adding them to their favorites.

The app also delivers notifications about events and new products from users' favorite stores, ensuring that they stay up to date with Mochikichi's latest offerings. Furthermore, the app provides exclusive coupons that are only available through the app.

Users can register their enjoyment cards issued by the stores in the app, allowing them to use the app as a replacement for the physical cards. Moreover, users can collect miles by participating in a daily scratch game, and these miles can be exchanged for special discounts.

To receive the latest updates, users can enable push notifications. Some features are exclusive to app members, so users are encouraged to register after downloading the app to fully utilize its functionalities.
