These are widgets per se and you'll need to search for each apk since I don't think they are available in the app store.
A great way to dress up (minimalistic) and organize/save space (circle launcher) on the home screen, the latter which helps with 7" tablets.
I haven't tried minimalistic yet but circle launcer works great. You can have as many circle launchers as you want. Just name them appropriately, for example I have one for games and news for now and put apps in each one respectively.

And of course you need to have an alternate launcher (ie. Go Launcher) to do this.
