The ホームセンターかんぶん公式アプリ, also known as the "かんぶんアプリ," is designed to make shopping at the KAMBUN K.K. home center more convenient and cost-effective. Users can switch from the "かんぶん Point Card" or register anew within the app to access features like displaying the card's barcode and point balance, effectively using the app in place of the physical card. This versatile app offers notifications for advantageous information such as flyers, coupons, and the ability to manage paper receipts digitally through Smart Receipt, along with daily scratch-off lottery challenges.

The app's key features include the ability to manage the "かんぶん Point Card," allowing users to display the card's barcode and point balance by switching from an existing card or registering a new one within the app. At the checkout, users can use the app's member barcode instead of the physical card. Accumulated points are redeemable in increments of 500 points for a "かんぶん Shopping Voucher" worth 500 yen. Users can also search for stores, view current flyers, receive push notifications for the latest promotions, access coupons, and participate in daily scratch-off lottery challenges for rewards.
