The Mansoku Card Official App, available on Android, is designed for ramen enthusiasts, allowing users to collect stamps for rewards at participating ramen shops. For every bowl of ramen purchased, users earn one stamp, and accumulating ten stamps grants a 500 yen discount coupon. The app also features special stamp lotteries at various locations on designated days, offering users the chance to win additional stamps.

Additional functionalities include a coupon system for discounts at stores, a store locator using the device's current location, and menu information for each participating shop. Users will receive notifications about campaigns and special offers. The app requires permission for location access to enhance user experience, ensuring that personal information remains confidential and secure.
