The Manto Card official app is designed for ramen enthusiasts, allowing users to collect stamps with each ramen purchase. Users receive one stamp per bowl, and after collecting ten stamps, they can redeem a coupon worth 500 yen off their next ramen order. The app also features special stamp lotteries held on specific dates at participating stores, where users can win up to three additional stamps.

In addition to the stamp program, the app provides users with valuable features such as store search based on current location, menu information for each participating restaurant, and push notifications for promotions and campaigns. Users can enjoy exclusive coupons at various ramen shops, enhancing their dining experience while keeping track of their rewards conveniently through their iPhone.
