지역화폐 사용처 is a free iPhone app developed by Taehyeon Han. It aims to promote the use of local currency by providing information about approximately 580,000 businesses.

The app primarily focuses on providing information about businesses that accept local currency in South Korea. It requires a Korean language address for the businesses, making the service exclusively available in Korean.

With 지역화폐 사용처, users can easily locate businesses that accept local currency in their respective city or district. The app displays the current address on a map, with pins generated within a 150-meter radius. Users can also search for businesses using their address or business name. The app offers a filtering feature, allowing users to view businesses based on their preferred industry. Additionally, users can customize the map display by selecting specific industries.

The app goes beyond just providing information; it also offers navigation to the selected business, ensuring users can easily find their way. A side menu provides easy access to various features, and starting from iOS 13, the app supports Dark Mode.

To utilize the app's features fully, users must grant the app access to their location information, as it requires this data to provide accurate city and district information.

While the app currently focuses on the Gyeonggi Province, future updates are expected to expand its coverage to other regions.
