Since 2018, the app has gone through a few overhauls. The older shows have been downplayed to advertise more recent brands like Dora the Explorer and PAW Patrol. Games and activities based on the newer brands were added, making the app less like a streaming service and more like a smaller port of NickJr.com.
Noggin.com, the old website for the Noggin channel, was relaunched in 2015 as a guide to the app. It now includes info and photos from various Noggin shows.
There have been a few TV commercials for the app. In mid-2015, one called "Get Started" premiered across all of Nickelodeon's channels. It features the host, Moose A. Moose, singing while he travels the world. Oobi pops out of a window, dancing along to the music. Later, at the end of the ad, clips from "Sing!" are shown playing on a tablet. The full commercial can be watched here.

None of the Oobi shorts have ever been released to the app. With the change in focus from older to newer shows, they will probably never be added.
