마트킹 is a lifestyle shopping app developed by nadl.kr for Android devices. It aims to support local supermarkets in their transformation and compete against large-scale retailers and SSMs (super super markets). With the backing of the Small and Medium Business Administration and the Korea Small Business Institute, 마트킹 is focused on reviving neighborhood streets and boosting the local economy.

마트킹 offers a unique wholesale shopping experience, allowing users to browse and purchase a wide range of products at the lowest prices. By connecting consumers directly with local supermarkets, the app promotes community engagement and supports small businesses. With 마트킹, users can easily find and purchase groceries, household items, and other essentials from their neighborhood supermarkets, contributing to the growth and vitality of their local economy.
