One Store is an app store similar to TapTap, TuTuapp. Now you can download many apps and games onto your Android device. And not only that, it also lets you listen to music, rent movies, watch TV series and much more. All through a very clear, easy-to-use interface.
From the drop-down menu on the left you can quickly access the different sections available in One Store. You can also use the search box if you know the name of the appor game you're interested in. However, you'll need to enter the name in Korean.
In the tab of each game and application, you'll get to see videos and screenshots, as well as the size of the APK, and the date of the last update. Just click on the big button at the bottom of the interface to start downloading.
One Store is an excellent alternative 'marketplace', providing you with a multitude of apps and Korean games, that are otherwise unavailable via other download portals. On the other hand, there are also many Western games and apps that you won't find here.
