The さいたま市みんなのアプリ, developed by FELICA POCKET MARKETING INC., aims to enhance the convenience of residents' daily lives, improve administrative services, and boost the local economy in Saitama City. This app serves as a platform to connect people, goods, events, time, money, and the city itself, fostering a community where mutual assistance creates a strong bond.

Users can access various administrative services provided by Saitama City Hall through the app, such as official announcements, library card services, and garbage collection schedules. Additionally, the app supports digital local currencies like "Sai Coin" for electronic payments at participating stores and "Tama Pon" for accumulating and redeeming points at affiliated shops and events.
