The Mos Burger App is a free Android application developed by MOS FOOD SERVICES INC. that features various functions such as member coupons, a GPS store locator, and a digital game. Registered members can enjoy exclusive coupons that are available for a limited time only. The app also allows users to connect with the smartphone site to view registered information and use both platforms to their specific needs.

One of the most significant features of the Mos Burger App is its GPS store locator. The app includes a GPS feature that helps users find the closest store. Users can also register the store they frequently use as their "My Store" to receive valuable information. Up to 20 "My Stores" are able to register. The app also offers a digital game called "Mossan," which is an original smartphone game.

It's important to note that this app is only available in Japanese, and coupons are only valid in Japanese Mos shops. The recommended environment for using this app is Android OS version 2.1 or later, but some content may not be viewable on some devices. MOS FOOD SERVICES INC. is actively upgrading the app version as needed, so users are advised to be patient while waiting for updates.
