The てんちかポイントアプリ is designed for iPhone users who frequent participating stores in the Tenjin Underground Shopping Mall. This free lifestyle application allows users to earn points for every 110 yen spent, with each point equating to one yen that can be redeemed at various locations. Users can easily check their point balance within the app, although some stores may be excluded from the program.

In addition to point accumulation, the app provides exclusive coupons for participating stores, which can be saved in a favorites section for quick access. Users will also receive push notifications for the latest news and campaigns. A unique feature includes a daily fortune check, adding an engaging element to the shopping experience. Registration and login are required to access certain features, and the app may request location permissions for optimal service.
