머스타드mustad is an advertising solution designed specifically for business owners. Developed by LG SILICON VALLEY LAB, this free iPhone app helps business owners create high-quality advertising designs in just one minute. The app offers a variety of templates for different industries such as restaurants, cafes, and online shops. Users can easily create designs for SNS images, promotional ads, menus, and more.

In addition to the design features, 머스타드mustad also offers affordable advertising options for businesses. For a minimum of 15,000 KRW, business owners can advertise their store on a 65-inch display board at major subway stations in Seoul for a minimum of two weeks. The app also offers an option to promote your business in hotspots around your area for a minimum of 10,000 KRW per week. Currently, the service is limited to Gangnam and Seocho districts, but the company plans to expand its coverage in the future.

Please note that the app requires access to your location to display store locations accurately and to broadcast content on other displays within the same wireless network.
