MartYo is a free Android application developed by Sejong Telecom. It falls under the Lifestyle category and is a perfect shopping companion for those who want to avoid the hassle of going to the mart. The app allows you to browse products, place orders, and make payments from the comfort of your home.

The app's main feature is setting your "Local Mart," which helps you receive discount information, coupons, and same-day delivery services from your favorite mart. With MartYo, you can also enjoy the same services as those offered by large marts in your neighborhood. You can quickly browse the product categories and check out the discounts and promotions in the "Event" section. You can also save your favorite products in the "Favorites" section for quick access.

MartYo requires access to your phone and storage to manage app settings and collect information. However, these permissions are only necessary and mandatory for the app to function correctly. Users of Android OS 6.0 or lower may need to upgrade their operating system and reinstall the app to set access permissions properly.

Overall, MartYo is an excellent app for those who prefer shopping from their homes. With its user-friendly interface, you can enjoy the convenience of shopping from your favorite mart without leaving your home.
