The Galaxy Apps interface is similar to Google Play's interface: the search bar is located at the top of the screen with different tabs right below it. With these tabs, you can quickly filter apps, video games, exclusive offers, and wearable apps. You'll also find a ton of screenshots for each app, as well as a description written by the developer and all the specifications you'll need in order to use it.
Galaxy Apps is an interesting app store for anyone with a Samsung smartphone. Other Android users probably won't benefit from this app, since you'll need a Samsung user account in order to download any of the apps included here.
